Uv-5R Bluetooth

Hi guys thanks in advance. I ride a XV1100 motorcycle in the group I ride with several have the baofeng UV-5R radio’s . Ok so I thought why not they’re cheap no worries. With that said I have had difficulties which were overcome. Now the guys have moved into a higher bracket. Sena-- I don’t dispute these are great units.However my budget does not allow me to go that far. So what it amounts to has anyone used the Baofeng add on Bluetooth that is available.
If so what have they been like for you?
Cheers Campbell
