I calibrated mine in both the blue and green wavelengths, but don't have good way to calibrate the red end of the spectrum due to lack of a know wavelength source in that range. It takes time and effort to collect meaningful performance data and write a quality review -- If you found this review helpful please vote 'Yes!"
"Also if the light source is not very bright then you might not be able to see the scale since it uses ambient light to make it visible."
"However, it is still useful for what I wanted -- checking the smoothness of the light from LED lamps and CFLs."
"Good for rating light color temps."
"This spectroscope is fun and easy to use."
"Works well, wish gradients were further defined."
"This item is also a useful photography accessory - if you plan on using a light, a quick check of the spectra can give you an idea of how good the colors will be."
"Seeing how different light sources give out light at various parts of the spectrum amazes me."
The spectroscope works by light entering a slight which then a view observes the light a diffraction grating and see through the diffraction grating to a wavelength scale.

Best Lab Power Supplies

Find Best Price at Amazon"I tested it with my Fluke 87V, and was very surprised to see that the reading on my meeter and power supply matched! The build quality is also good, both the outside case and the electronics appear well made. The LEDs for the CC and CV don't line up with the holes in the front panel."
"My only issue has been with forgetting how the controls default to changing the most significant digit when rotated."
"My initial impression is that it has excellent build quality on the exterior (I haven't opened up the unit to see the internal layout, and I ..the buttons and controls feel very good, and the display is clear and bright."
"After the unit is turned on the blinking digit to adjust both the voltage and the current is the left or most significant digit. This means that, for example, if you are using this power supply with a 3.3v system the default adjustment digit after turning it on is the 10's digit and it's very, very easy to accidently turn the knob when you are trying to push it to select the next digit. The unit does remember the last digit that you selected from the previous adjustment which is nice but it does not remember this after the unit is turned off and back on. If there was even a short interruption in the A/C power the unit will come back up to the desired voltage but if you didn't realize this and pressed the voltage adjust knob and turn it thinking you were adjusting the same digit that you just previously did, poof. The second issue is that although the Lock function works great and prevents adjusting the voltage or current when this indicator is on, it does not remember this setting if the unit is turned off and back on."

"I have been previously using an Omron Body Fat scale since at least 5 years but I was growing increasingly discontent of it because its reading are all over the place. So 1 Lb of fat inaccuracy is a lot when you monitor yourself daily... Let me pause for a second to state the obvious: No Body Fat scale is truly accurate to a very high degree but consistency is important. This is why after so many years I started searching if there was anything better on the market and here comes the Greater Goods Scale. Compared to the Omron, this scale shows me variations of 0.1% of my body muscle or fat within 2 days when the Omron would jump up or down 2-3% in the worst cases and 0.5% in the best cases..."
"I love that I'm able to keep track of more than just "weight" on this scale. ), then when I stepped on the scale it recorded my weight and slowly cycled through each measurement - BMI, body fat, muscle mass, etc. It was super helpful not just to set up (because that was very easy), but it has a lot of good information on what the scale measures, the average ranges of each measurement, and some troubleshooting/FAQs."
"my weight and BMI numbers registered new numbers but the water did not."

"I am very pleased with the 20 gal Marineland. fish tank."
"Getting it on a good deal, I didn't mind spending another $60 on gravel, plants, decorations and start up chemicals. While it comes with a sample of the water conditioner, I also added a safe start solution with bacteria. My light strip will not snap into place, and threatens to jump ship each time I open the lid to feed."
"The fish are growing beautifully, and I feel so sorry for the fish in the huge tank in the store who are just going to end their short lives as food. I will eventually upgrade in size for these guys but feel very sorry for rest of the fish left behind in those "feeder" tanks - stressful lives filled with disease among hundreds of other fish for a short and miserable life. 12-29-16: I am very grateful to the other reviewers who pointed out that the water from the filter splashes back up onto the light connection which eventually destroys the light. Hopefully this continues to work and can help people have the light to have plants to enrich their fish' lives."
"The filter is so much easier to clean, and replace the filters."
"Last night I took the whole filter out to clean it and when I put it back together, it didn't work. And then tonight I fed my fish and went to turn on the blue LED night time lights and "surprise" that stopped working as well, along with the regular LED lights. Tomorrow morning I'm off to the local pet store again to buy replacement equipment."

"The MAXL seems to be the best single-cartridge (but 2-stage) water filter I could find. The answer is: Faucet and hardware (to install in an available hole in your sink), hoses to connect to both the new faucet and to the water supply, green plastic mount that connects the cartridge to the hoses and attaches to the wall, T adapter that goes between the shutoff valve and the existing faucet's cold water hose, and a little "6 month" reminder timer strip."
"These pipes have tons of advantages over copper pipes, but we found that our water tasted TERRIBLE, like chemical-laden plastic."
"However, I do recommend (as we did and many other reviewers) to get it professionally installed and have the plumber use their parts in place of some of these flimsy connectors."

Reviews
Find Best Price at Amazon"Having this in my basement was extremely eye opening, showing me that: -The radon mitigation fan that was installed in my house, which is working in the green (according to its vacuum indicator), does essentially nothing to reduce radon levels. The average radon level in your house over a week or month is meaningless when it can change so drastically month to month. With it on, a few windows cracked, and the central air intake in the basement sealed to increase relative pressure, I've managed to get radon averages from 5 pCi/L (dangerous) to 0.50 pCi/L (safe) regardless of the heater occasionally running."
"The Corentium and the SS were turned on at the same time and allowed to run until the SS started to show a result (due to the SS not showing an initial reading until a couple days after turning it on or resetting it, whereas the Corentium starts showing a reading almost immediately). Then I sealed up the charcoal tests and mailed them in and checked the readings of the Corentium and the SS which had now been on for 7-days (the reason for 7 days is that the devices both provide readings at 7 days but other readings are at different time parameters and so not comparable). Charcoal Test #1: <0.5 pCi/L. Charcoal Test #2: <0.6 pCi/L. Corentium 223: 0.97 pCi/L ("7 days" reading). Safety Siren: 1.2 pCi/L ("S"=7 days reading). Please note that I bought both the Corentium and the SS in March 2014 and so both were almost 2 years old at this point. I'm not sure the charcoal test results and those of the Corentium and the SS can be compared directly since their readings are over different times (approximate 4 days for the charcoal test vs 7 days for the two devices; I had to do this since the charcoal tests cannot be tested for more then 4 days and the two devices do not show readings at shorter times (e.g. 3 days, etc.). Interpreting the results is not exactly easy or maybe even valid, but it does at least seem to show that the devices are not wildly different than the charcoal readings and more importantly, they seem to read higher rather than lower than the charcoal readings (i.e. they do not give falsely low readings). ---. [Original Review: April 2014]. Just want to point out that this radon detector does not wait for a couple days to give an initial radon reading, like some detectors do (like the Safety Siren Pro Series3 Radon Gas Detector - HS71512 by Family Safety Products, Inc. does), so basically within a minute or so of turning this device on for the first time (or after resetting), you will start to get initial readings that are predictably around 0.00 pCi/L. Over the next couple days (again, the initial readings were after 2 days already), the Corentium reading starting to creep upwards, going from mid-0.5s to around 1.0 and then above, while the Safety Siren Pro stayed fairly steady around 1.7 Another couple days may bring the Corentium to around the reading of the Safety Siren Pro, which would make me feel better that they're both reliable if given enough time."
"Fast forward a few years, I did some minor basement renovations to remove batt insulation between the exterior rim joists and install a DIY spray foam seal, and replaced my window well windows with dual pane vinyl inserts. I bought the Corentium unit, because of the great reviews and easy continuous monitoring. I was surprised the Corentium reported high levels even in the upper floors of my house. I have loaned the unit to friends, family, and neighbors to help them make informed decisions."

They'd through the bar, it was hard to find the correct potentiometers for the power supplies, etc. 4.Power supply is separate from the plate itself, making it easy to clean and pack away. The top surface is hard plastic and kinda slick, even with the moulded texture. I'd like a grippier, rubber surface to hold on to my often wet, glass container. I'm defiantly going to find a thin rubber sheet and glue it to the top of thee stirrer. There are only a few things I'd change if I designed it but it's totally functional and for the price compared to other commercial stirrers, you can't beat it."
"The stir bar immediately found the base and had a very decent whirlpool at only a quarter of the way on the speed control. Anything close to full power will throw the bar in plain water or a standard 1.042 starter wort, but if you are working with a highly flocculant yeast or a thicker solution, this should come in handy. I would highly recommend to any brewer out there looking to replace a DIY project for a fairly priced, quality made stir plate."
"Very compact, the magnetic stir bar feels very secure on the plate, easy to operate."
"It feels like a very sturdy unit and comes with 2 stirrers (a small rectangular rod and little larger hexagonal bar) The only issue I have is that the small stirring rod had a crack in the plastic - probably just a manufacturing error or it got damaged in shipping."
"It has plenty enough power, even with the concave bottom of the container, to deliver amazing stirring capacity in a 5 liter container!"
