Product review (3 stars): Patience is a virtue they say
Nice idea but would be great if it worked consistently.  On any given day it will send several updates of 'device not been seen' and then will give several updates on temperature (max/min) so it appears to loose contact and then regain again a lot.  Some days it will not regain signal and has to be restarted, which has to be done physically at the device.  App is okay but does not refresh temp without logging out and back in again ( at least that's the only way i have been able to get a 'current' real time temp to show).  Over all is a good buy if you are willing to deal with the inconsistencies but could be so much better.
