Just received my Maverick ET-735 last week (ordered off of Amazon....should have ordered from a Forum member). I wanted to use it with my new UDS builds that we are completing, and had really high hopes for this product. Unfortunately, it appears i have been let down. I can't seem to get the app to connect with the transmitter, and when i do, it tells me there are no probes connected. The fact that it ships without an instruction guide, is pretty comical (as how can i read an instruction manual on my phone, while fumbling through app and phone settings. My only regret is that I didn't keep the box, so i could return the product (tossed it in a bit of drunken competition bbq rage). I might try it with another phone or two (I was trying to use it with a Samsung Galaxy S5 Active....and got no love), just to see.....but as of right now, i am not impressed at all.
I did breakdown, that same day after discovering the ET-735 may be more hassle than it is worth given the software, and purchase an ET-733. I fired that up right away, and had no issues. However, several at the BBQ comp that I was at told me that they can't use wireless mavericks because they will pick up other competitors sensors. That exact issue was what i was trying to avoid by purchasing the ET-735 (well that and being able to monitor 4 probes would have been cool).
