Good item.

Bought 2, and testing shows both read the same, which is good.
Finding range and connection is fine, if close to vehicle i installed one in(so will be great for tests while using vehicle).
But range is a bit less than i hoped for, with it currently being mounted under the metal bonnet, so it's being shielded a fair bit.
Messages from it work fine, if it's left in range(beside closest window for me, with vehicle 4 meters away).
May try mounting inside it next, (by widescreen).
Overall, a very good value product.
One very minor issue i have is, with my phone(Huawei p30pro), complaining about it being a power intensive app, if left on, even though history shows it draws very little, but i have the same issue with others items as well (6x govee temperature/humidity readers) giving repeat notifications about it, so therefore not a product problem.(cannot find a setting in phone, to ignore only that message)
