Both films I received work properly and without burnt or empty LEDs on the strip, which is not so common in economical LED strips.
The color settings from the remote control are very good.
The adhesive is moderate to good. The same strip purchased 2 years ago works perfectly even with moderate use.
The price/quality ratio is very good

For their price, they are relatively good. I have had them for about 3-4 months and they hold up, just some LEDs burned out in between and I cut them off, connected the remaining ones with a link, and they still work fine.
