I have one. I was looking forward to the graphing capability, but when your phone goes to sleep, the graph stops. Range is pretty good for bluetooth, but no better than my previous thermopro with a dedicated receiver. I do like having 4 probes, the temp alarms are good, and I tested mine with ice water and boiling water and it was within a 1/2 degree, so I am basically happy with it. I bought mine back in early July, and I think it is pretty good for the price.
