Excellent to deal with

Excellent to deal with. Being able to get my battery from a new zealand company who actually had stock made the process so much easier!
Many thanks for the fast service.

Easy to use radio earset

They do what they say they do, easy to use and no extra gear. The main set is the master and needs to be used, just turn them on with charged batteries and they just work. We have tested them to about 400m but really only need them for up to about 100m max and they work really well, easy to hear everyone using them. Once they are on you just talk and listen, there are no buttons to push
We use the single ear so we can hear people not using the sets.

Prompt Service and Friendly Comms

Prompt service and friendly comms. Speedy delivery (over night courier).

The radios were well packaged, received un-damaged and presented well. I'm happy with the radios and find no fault with them so far.
