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."
"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."
"However, as others have mentioned, there are some frustrating design flaws that make it dangerous to use without taking special precautions. Changing adjustment units (10v to 1v to .1v to .01v) requires repeated knob pushes WITHOUT rotation. Recommendation 3: Remember crucial options like the voltage adjust units and Settings Lock across power cycles. Issues #1 and #2 would be somewhat mitigated if there were an Output On/Off switch to easily disconnect the supply from the circuit before making ANY setting changes. I opened the unit to see if I could add a switch myself, but it'd be difficult given the main logic board encompasses almost the entire front panel. The only real workaround for these flaws is to manually unplug the positive banana plug before making any changes and then replug it in only after ASSURING the new settings are correct. It is frustrating that what is seemingly a robust and well-built power supply is dangerous to use in real world situations because of some basic human interface design flaws."
Eventek KPS DC power supply could be used for electro etching. The output voltage and current are continuously adjustable at nominal value. Do not operate in humid environment Do not operate in flammable and explosive environment Keep the product surface clean and dry It has a switch to flip between 110v and 220v (when 220v,you get 24v max , and when 110v, you will get 30v) The unit was set to 220VAC input so the output voltage (when powered w/ 120VAC) was mucked up.

"Plus, I've read horror stories about different USB cables being faulty and getting fried by even just the amount of current that comes from a standard wall outlet. The first thing that struck me about this variable DC power supply, made by Eventek, was that it's relatively compact, but still feels substantial. But the fan kicks in when it detects that the unit is getting to a certain heat level, ensuring safe operation. If you're interested in getting a variable power supply, I highly recommend this unit by Eventek. Not only is it high-quality and well-made with all the essential safety features, it's relatively small and portable for the power levels it can put out, which really impressed me."
"I really like this power supply."
"- as advertised voltage range and current limit, from my testing, the voltage can deliver up to 30V and current limit can even go slightly above 5A. - satisfactory accuracy, the meter for voltage and current though have 3 digits, that is still accurate enough for home/small lab usage. For this power supply and its features and quality provided, it is definitely a good buy for the price it asked for, recommended!"
"Front view operating in voltage mode set to 15V (no load). 2."
"The display read out size makes it easy to see the numbers for adjustments."
"The power supply came with the power cord, plus two test leads."
"This power supply is light to move around to accomplish this task."

But if you're looking for clean low ripple, low noise power supply this is not it. Some reviewers wrote that the power supply had overshoot on power on, I certainly did not measure any with my oscilloscope."
"I absolutely love this mini 8 in one pocket knife the knife is super sharp can be used in emergency situations i like that the bits are magnetic and can be easily removed also the bottle opener works as well i like that it came with a carrying pouch to carry around it can be easily opened the flashlight is super bright and i simply love it."
"So far I have had zero issues with the power supply. Pulling the unit out of the box I noted that it was heavy for its size and solidly built."
"Unnecessarily noisy... Just put some heatsink fins out the back already... Update: had to stop using the provided leads."
"As one should always do, check your voltage and current settings at first power up."
"The knife has a great light brown metal color, yellow button for the built in LED light and the black plastic housing for the screw bits."
"Be extremely careful when adjusting the voltage, it's easy to jump 5 without even trying."
"Could not get anywhere near stated max current and voltage."

Find Best Price at Amazon"Worked great for getting the nasty grunge out of the nose pads on my eyeglasses. We haven't used it on my wife's jewelry much because of the various recommendations out there about putting gemstones (and synthetic ones) into an ultrasonic cleaner. The glasses are 3 years old and had a couple of small, but obvious paint chips from wear and tear. Apparently there were a lot of very small rough spots in the paint after 3 years and the ultrasonics "cleaned them" off the glasses entirely."
"Using just soap and water to clean it did not make me feel confident that it was thoroughly clean, so I just pop it into the machine in the morning with water and a drop of dish soap, leave it on for about 4 minutes, and then I'm ready for the next night."
"I cleaned all my jewelry and glasses and the jewelry sparkles and the glasses are squeaky clean."
"I could see really tiny bubbles of air moving (vibrating) the sludge out of the dichroic reed tunnels, cleaning the inside of the to-be-fire-polished pieces."
"People LOVE receiving them because they aren't an item that they would ever think to get themselves."
"Tomorrow I'm going to clean my jewelry and my husband wants to clean his watch. I would definitely recommend this to anyone who wants clean eyeglasses and jewelry."
"I do not believe it is the right item to clean silver (as a previous reviewer tried to do) I would purchase one of the plates to use in hot water, I have found that's the easiest way to clean silver."

"I haven't opened the 10 lb bag of citric acid yet because the 5 lb bag I had isn't empty yet."
"I bought it as a way to clean out my dish washer and I use it for a quick rinse before washing."
"Came with a slight tear in the bag, but that's not the manufacturers fault, except they could have used slightly thicker material."
"I mainly use citric acid to clean my water well system and it works GREAT."
"Works for what I need it for, but this is the 2nd bag that has come with a slice in the bag and it's everywhere in the box, what a mess!!!"
"Great deal but product arrived busted."
"The company's product is good (I use their smaller bags), this just wasn't the best delivery/storage system."

"NSF rated (A little taller than table or counter height--especially with he additional wheels."
"The table legs and shelf are packed inside the bottom of the top of the table, and the legs are individually wrapped. I received all parts necessary to assembling the table & even got an extra leg bracket (where the leg fits into the shelf)."
"Comparing the price of this to others I thought I would be getting what I paid for, but I couldn't justify spending the big $$ for a rolling table. This table came packed in a a nice box, all of the parts were in it and it is super simple to put together. The table top is a nice quality wood that is clear coated and smooth. The reason I bought this table was to use with my brand new UUNI Pro Pizza Oven. The UUNI has stainless steel legs that are somewhat slippery when sitting on top of this table. I stuck some rubber feet on the legs and it holds the oven in place perfectly. The wheels are a nice size and will roll over most stuff (concrete, decks, etc), but if you need to push it over grass they may be too small."
"We mounted the dishwasher on this cart, load the dishes in the kitchen, and the cart wheels easily into the bathroom where the dishes are washed."
"Great height for working while standing as well as while sitting on the adjustable stainless steel work stool that this company also offers."
