"Work great for arduino projects, comes with plenty of extra diodes."
"Really handy to have around, they handle a fair bit of current and the included diodes are great for controlling voltage spikes coming from motors/coils."
"Just what I needed to finish my project."
"Works great."

The product type is Major Brands TIP120-R Transistor, Tip 120, NPN Power, Darlington.

"Nice assortment of devices to help the maker or kit builder."
"It would be considerate of the seller to put out a folder with all the spec sheets so we don't each have to spend an hour googling and downloading."
"Great assortment of general purpose transistors, NPN and with complimentary PNP in most cases."
"Good assortment and quantity of popular npn and pnp transistors."
"quality choice for my work shop, love it."
"Good assortment."
"This kit looks great and has a ton of variations of transistors but the 2N2222 models (the most used/called for) seem to be either bad or have non standard pin outs for BCE."

"and auto fired, the other works great."
"Used this in an unregulated dual 18650 series box mod and it worked great despite taking quite a beating due to my crappy (though improving) soldering skills."
"Perfect for box mods with 1 or 2 18650 sized cells."
"This mosfet works flawlessly on my parallel unregulated box mod."
"It works great but don't let the picture fool you this part is a bit long and may need to be trimmed down to fit in a box mod."
"Unit shorted out after 3 min."
