In Tatarstan for 20 days. Packing is good. Each led in its package. I expected that the size will be more. The quality looks great. The case hasn't been checked yet.

Before that, I ordered from another seller matrix for 50R/PCs-uneven brightness of LEDs and, as a result, they worked 7-12 days (!!!). These are 5 times more expensive, the matrix shines evenly, the light is bright. Based on the results of operation I will write. Seller-thank you!

Finally got to these LEDs. The substrate is oxidized, without overheating of the matrix, in the air, becoming first yellow, and then brown-black. To expose mechanical loads I do not recommend, 150 grams of terminal block and wires, two LEDs are not transferred by my fault. The initial stage of oxidation can be seen on the pictures, Operation month, temperature about 45-55 degrees (jammed the power with a resistor of greater nominal value than necessary.
