Although the description says the working voltage is 2.7 - 5.5V, all 5 I got do not work at 3.3V. They start working around 3.9V. This is weird, because already used some identical looking items, and I think I got them from Banggood too, and the old ones work fine with 3.3V. The only visual difference is that the ones I already got have the number "159" on the back, while these are shown as "143". It wasn't a big deal for me, as I simply swapped some of these with the old ones (which were used in 5V circuits), but if you intend to use these with 3.3V, be warned - they might not work.
Good quality for good price. Works perfect.
