Out of the three I bought, none of them worked. In fact, each one has a different behavior. The first one had a detached cable that goes directly to the 18650 battery. Although it was soldered and turned on, it does not change program and remains permanently on regardless of day or night. The second one was installed and the panel almost sees the sun all day. However, it never turned on no matter which program I chose. The third one probably has a dead battery.

Easy installation, the lighting is not very strong (it covers a small balcony). However, for its price, it is a good purchase.

It has been used outdoors for two weeks, it has endured a lot of rain and it doesn't seem to be affected at all.
Easy installation, it also has a long enough cable to place the collector anywhere.
Its sensor is activated with the slightest movement, as it should be (with its pros and cons).
Strong light even on cloudy days, with slightly lower intensity.
It has a small button that, when pressed once, stays permanently on at full brightness, on the second press it stays permanently on at half brightness, and if the sensor is activated, it becomes full brightness, and on the third press it turns off and can only be activated by movement.
I highly recommend it, especially at this price.

Very satisfied really for the money, I have no complaints. If you want it for great coverage, don't get it, it's for short distance lighting. But I bought 3 and all 3 do a perfect job. I have put them in the entrance, staircase, and balcony and they are very good.

Quite satisfied with the product. Very important that the motion sensor does not work during the day but only at night. This way there is no unnecessary consumption and the batteries hold their charge.
