shipment came much faster than the estimated delivery date

I was hesitant to order direct from china but considering these are almost $2 each when you buy them in cali, I figured I'd give it a try. The estimated delivery date was more than a month from when I placed the order but they got to my place in 9 days. All 50 were in the pack. I wired one up to an arduino and it is VERY bright at full power. It's painful to look at actually. The color blend isn't great but very similar to other rgb non diffused LEDs. I sanded one and it diffuses nicely now just as a test. If you're wondering the specs, it seems like this is the data sheet people are talking about.

[...]

i used 5v from the arduino with a 147ohm (1x100 and 1x47) resistor to red and 100ohm to green and blue. That's operating towards the high end but with how bright these are you could use higher ohm resistors to make them use less power and bring them down to the lower operating range. I would definitely order more of these, maybe diffused if they offer them.

While the book came within the specified time, it took longer than normal.  Was hoping for a quicker delivery.

I'm from Colombia, and this shipment was delivered in my home very fast, before the estimated time, in perfect condition and very well packed. I'm happy with this purchase

It was great!  It came much sooner than the estimated date.  Unlike some of the other reviews I read, it was packaged perfectly and arrived undamaged.  I have not determined how well it works yet, as this is a Christmas gift for my daughter.

This shipment arrived faster than expected.  The only reason it's not 5 stars is because it's a gift and it'll be a while till I find out if a is well with it.
