If you have apple, do not buy UEI

I bought the hub6 and vacuum gauge and could not be more disappointed. All of my other tools are UEI and I figured this would be a great addition to my toolbox. I could not have been more wrong. I have owned the probes and vacuum gauge for four years now and they don’t work the majority of the time. Every time there is an app update or an Apple update none of my tools work. Do not waste your money on the hub sex or hobby if you have Apple. I’ve been waiting for a return email from support for two weeks with no response. I am hoping there will be some sort of class action lawsuit soon.

Tool sync

None of my tools will sync now. App is useless and so are the tools since they won’t communicate. Keeps telling me to turn on the Bluetooth when everything is on. Before the update everything worked great.

Terrible

Won’t connect to I phone, so good luck with that

Wireless gauges won’t even connect

Have had these gauges for over a month now and liked using them. After an app update now my 800$ wireless gauge set won’t even connect on my iPhone.
