Very sluggish to turn off when turned overUsed 4 times now does not run off when turned over

I've given this only two stars because the item listed wasn't the item I received. Superficially similar (although black not white), it has a different model number (XD-S001 / R200 instead of UY7857); it doesn't have the safety feature, so it stays on when pointed upwards; and its UV wavelength according to the manual is 260-280nm instead of 200-275nm.Apart from all that, it works as described and also comes with a stout polythene case and a standard USB 3.1 cable for charging. I'm not returning it because I don't care about the missing safety feature, and it does what I want it to do; I use it not as a sanitizer, but to check mineral samples to see whether they fluoresce under UV light (and some do most beautifully). The picture is of a sample that contains willemite, illuminated with the item.

This item is of great use to myself and my wife we use it in kitchen quite a lot
