So, finally StickNFind responded on Indiegogo and agreed to replace the stickers I have. It's very frustrating that they shut down all communication before.
Since the last update, the following appears to have happpened:
* If you update to iOS 7 without installing the latest StickNFind app and connecting to the stickers in iOS 6, you lost communication with the stickers. There is some secret way of fixing it that isn't published (the "magic sticker" mentioned below?). This was communicate to the users the day after iOS 7 was released.
* Android BLE still isn't working - there are bugs. The communication from StickNFind is quite aggressive about this - they just seem to want to pin the blame on Google and not keep customers informed.
* Communication, on the whole, is still very very bad.
I’ve had my replacement stickers for about 10 days now and have the following to report:
* 3 out of 4 would pair with my iPhone 5 running iOS 7.
* The remaining one wouldn't pair with a Samsung S4 or an iPad 3 running iOS6. Support is sending me a “magic sticker” to fix it.
* The new stickers have a stamped FCC ID on the case.
* The battery contacts are different – the centre one is sprung instead of just being a solder dot.
As for use:
* The three working stickers are more responsive than the old ones. They take ~30s to respond and seem to reliably respond. The old ones sometimes took 30s, sometimes 5 minutes, sometimes never.
* The range is still low. I can’t really leave a sticker downstairs and go upstairs without losing signal.
* When in leash mode, I get random activations even with the devices within a few feet.
* One of the tags seems to randomly go off without being on leash mode.
So in summary:
* It’s odd that one sticker was sent being incompatible with iOS 7 and needs fixing. (honestly, I am dubious – why wouldn’t it work with iOS 6 or Android if this was the case?)
* Why are these “magic stickers” not mentioned anywhere on the support pages?
* Responsiveness is improved
* Reliability is improved
* Range still seems poor
I couldn't recommend buying them still.
