It's been years, but I have ordered stuff from these guys on several occasions.
I guess you need to know that a lot of this stuff was unwanted for some reason. A lot of it is used. The used stuff is usually obvious. It also usually works OK. The new stuff is usually defective in some way. Kinda' like the stuff in the bin where no-esc works. Sometimes it's OK. Sometimes it's truly dumpster material. Way back in the day when blue LEDs were going for >= $3 each, I got a bag of blues from them. I think I paid $72 for a bag of LEDs. Technically, they were blue LEDs. If you turned out all the lights and looked directly at the die through the dome of the LED, you could see a tiny glow. In normal room light... nothing. They had to know this. I also got a bunch of line lump power supplies to light LED projects. Out of about a dozen or more, one or two of them still work. They do, however offer some stuff that you simply will not find anywhere else; and in some cases, you'll never see again in your life.
They had a sale on those little hand held fl tube black lights. I paid like $3 each for a bunch of them. That was a deal! Those things are fantastic for a quick blast of UV.
