I have the Swift Hitch camera system
click which looks similar to the iball, I've compared the two side by side and thought the Swift Hitch was a better built product overall and the range is remarkable, when I first got it I could get perfect reception from my kitchen all the way down to the utility room in my basement also the camera is all steel built with a weather-proofing cap for rain. I use it for hooking up my fiver as well as my pontoon boat trailer and my cargo trailer, I have a steel disc I mounted under the upper cabinet in front of my rear window in my fiver so it can be used as a back-up/rea camera as well, a true multi-tasker, I even used it to find a part I dropped under my pull-out couch in my fiver(it has great night vision).
