Pros: - very cheap
- good for repairing flashlights or other things that use LED.
- you get 25!
- pretty bright.
Cons: - no guide how to use them.
- you don't really use (need) them normally.
- they burn out if you don't know how to use them.
- comes in a plastic bag. (but for the price you could expect they wouln't come in a box or something)
Other Thoughts: should come with a user guide sheet or something, or info should be on the site for people who don't know how to use them.
use them with 4.5 Volts or lower!!
Bottomline: great LED's for a really good price, if you need to fix something, buy these!!

Pros: - Very bright small LED:s
- They are very cheap
- All of them worked
Cons: - Came in a bag, some legs where bent, still nothing that you couldn't bend back
- No marking on the bag, I ordered more than one sort of leds at the same time and had to guess which was which
Bottomline: - Fill up your storage, at this price you can easily afford to order more than you have use of for the moment!
- So bright that it hurts to look at them when they are driven by a 9V supply voltage and a 330 ohm resistor!
Very bright and cheap!

Pros: Very bright. Cheap. Can easily be used to build a flashlight powered by AA/AAA or 9V batteries, if you got the basic functionning knowledge. The ones I got have lower voltage drop of ~3.0V when compared to standard 3.2~3.6V white LED, which means you can use more of them in a series than when using standard ones and have lower power dissipation on a resistor... well, they are so cheap that you probably won't mind not using a resistor if you're connecting them to a 3, 6, 9 or 12V nominal voltage battery (2*AA/AAA or 9V or lead-acid battery or even PC ATX Power Supply 12V rails).
Cons: The small viewing angle, as far as I can tell I can't see any real cons beyond this one. I'm planning to solder a bunch of them to a PCB and then use sandpaper on some plastic or buying a plastic enclosure of a specific texture to help diffusing the LED light and/or change its color to a yellower one (warm white).
Other Thoughts: I got one pack with 24 LED, another with 26. Well, in this case I got what I ordered, but if it were one or two packs with only 24 LEDs, I would have payed for one/two more that I wouldn't receive.
Bottomline: Much much much more cheaper that local town's electronic store... and brighter.
Cheap and High Quality

Pros: These were bought to use in a project and I actually ended up with leftovers as they were a lot brighter than I expected them to be.
Cons: Would be nice if the specs were on the site or on a piece of paper with the LED's.
Other Thoughts: When they arrived they were neatly packed in bubble wrap and in a bubble wrap envelope.
Bottomline: This was a good buy and for the price you can't go wrong. I will be purchasing more when needed.
I'm running the LED's in a parallel circuit with a 9 volt battery to power them.
