"It comes with a large assortment of parts."
"When you give kids the opportunity to figure things out, experiment, take risks, and direct their own learning, they are so much more engaged, and learn at a deeper level! I've had the kit for a little under a week, and the students have completed three different projects builds. They found lots of ideas, but then had to narrow it down to beginner level projects. It didn't take them long to figure out the programming requirements, and then they were up and running!"
"Not only does it include all of the usual 'introductory' components, but also several components that can be used on real applications as well as more advanced tutorials. The board was recognized by the Arduino IDE without issues, The item description has a list of the components included and you can see there is a wide variety of them. The lack of documentation really hurts the kit, as some of the components do require more knowledge than is usually found on the first results of a google search, but the info is out there. Despite the lack of documentation I still highly recommend this kit, not only is the number and variety of components excellent, they cover a wide gamut of applications, from basic accessories (breadboard, battery holder, jumper cables) to the esoteric (RFID kit), including a couple of motors (which are always fun to work with)."

"A very dark red PLA."
"I've been printing at 205C and a 60C bed temp with no clogs, layering issues or other problems on Prusa i3 & Robo R2 printers."
"This is a nice red."
"Came vacuum packed with silica gel packet like most premium rolls."
"Works well with my CR-10 printer."
"Not my favorite shade of red given that it makes parts that look like tomato paste."
"5star quality color!"
As for value well for what they are they seem pricy but when you need some custom size jumpers or have a complex project with a lot of jumpers need to keep your wiring manageable then this is a steal.

"Perfect for prototyping."
"Very nice set of preformed jumper wires for projects and prototyping."
"Absolutely fantastic wire organizer."
"Good quality."
"I really like using these jumper wires as they good for handling higher amperage for relay setups."

Hopefully this helps with whatever issues you may be having: Power Up - Long Pulse (2 seconds). Polling Open - Successful Response - Long Pulse (1 second). Polling Open - Valid Response - Long Pulse (2 seconds). Polling Open - Invalid Response - 3 Short Pulses (0.5 second each). Polling Closed/Invalid Answer Type - Short Pulse (0.25 second). Change Channel - Success - Short Pulse when GO is pressed (0.5 second) Long Pulse after successful change (1 second). Change Channel - Invalid - 3 Short Pulses (0.5 second each). Change Channel - 5 second timeout - 3 Short Pulses (0.5 second each). Receiver Not Present - 10 second timeout followed by 3 Short Pulses (0.5 second each)."
