I had brought this particular one from China when it first came out 3-4 years ago and it still holds up. It successfully stayed in the garden for 2 years fully exposed to the weather conditions. I believe it has a very good construction and it is indeed built to last. It has 2 functions, one with warm light and one that slowly changes colors. The color changing rate is calm, not strobe. It does not have a motion sensor, only a night sensor. Meaning it turns on by itself when the sun sets and turns off when it rises. I do consider it quite expensive at almost €25 at the moment. It is worth it if someone is not just looking to light up a space but wants to give it a nice touch. If you just want light, there are more value for money products available.
