This product is simply bad design. Not only did it arrive with dead batteries, but the replacement battery feature in the app is also broken - it comes in a pack of 5 pixels, and each of them have to be connected before the app can determine that the battery is dead, so if the battery is dead on arrival, there's no chance of getting a replacement for free as advertised. Plus, you can't order multiple batteries even though there's no way you can buy a single TrackR pixel, they only come in multiple packs.
After purchasing replacement batteries, getting into the pixel to install a new battery is a mission because of the terrible design. The back is meant to twist open, but that's just a lie. There's no way for your fingers to grab on or even have any traction against the back to twist it open. After finally managing to get a new battery in, the product design is such that it doesn't let the battery touch the circuit board, so unless I squeeze the pixel really hard, it does not turn on. Overpriced, completely useless, a total waste of plastic. The idea is good, but the execution fails completely. This is like a high school product design assignment gone wrong, even the basics fail miserably. When I tried to contact the manufacturers through their website, literally no leads as to how to contact them. Do not buy this, it's basically a scam given the way it doesn't work in any aspect - product design, customer service and replacement services are all a giant failure.
I never post reviews, but these fail so badly that other people must be told how awful it is.
