I have a few rugged phones recently purchased. Oukitel WP22. Ulefone 18 Ultra. Tripltek 9. I decided to do a deep technical comparison of them. Every time I see a review there always seems to be important info missing. What good are elegant curves if you cant get a signal. How well does the camera work in difficult conditions? What is the point of a loud speaker if the quality is unlistenable. How sensitive is the radio? What is the point of 4K recording if the accompanying sound is too muffled to hear? How long does the battery last in real usage outside the laboratory?

Thought I would post a video of the transmitter kit production. Each kit is 100% hand made in the USA and thoroughly checked before shipping to make sure everything works and is included. Each kit takes between 6 to 8 hours to prepare. Full high resolution color instructions are included on a usb stick. All you need to do is assemble the main PCB. Each kit is backed by our unique build guarantee. If after some diagnosis you are unable to get it working, you can send it to me and I'll do a free repair. No shipping back to China and waiting weeks for a working transmitter! Everything is included to get you on the air. No need to buy power supplies, Audio cables Antenna tuners and power meters.
