Happybuy Wireless RV Leveler for Android

Very good. Works well as described. A user will have to be slightly handy to do a permanent install in their RV or trailer.I also found the bottom of the blue case of my level was not "level", it was round, so just sitting it on a counter it would rock front to back by over 3 degrees. After screwing it down, it behaved reasonably. I believe it was the rpocess of molding the case that caused it to be rounded on the mounting surface.I believe it is much to hypersensitive to movement, as this is not a drone gyro unit, it's for a trailer. No need for 0.02° degrees measurement!!The extreme sensitivity makes the female robot voice annoying so i keep that off and look at a tablet for leveling.The level makes it fast and easy to pull forward onto a dual axle wheel leveling plastic block and stop where needed.Then leveling front to back is easy enough, just have to have the tablet with me when using the electric tongue jack.

We picked up the Travel Trailer on the 29th of April and backed it into the driveway. I got out the two four foot beam levels I haveand began the tedious process of leveling the trailer. It took me about an hour, and that was after studying hours of youtube videos.Once it was level, I installed the RV Level device. Under the oven is a panel that is held in by 4 screws. Pulled that off and there wasbevy of wiring there. Found the 12dc pair I could use, tied it in and set it up. Since the beam levels were dead spot on, we zeroedthe settings and were done.Then, on the 5th of May (please, no Jokes), we headed for the State Park for our shakedown cruise! Once there we filled the freshwater tank and headed for our site. We backed in pretty easy and I checked the app on my Droid Turbo... BAM! 3 inches low on thepassenger side! Put out the leveling blocks, pulled up on them, DONE! Unhitched and set the front to back level with the powertongue jack and we were camping... took about ten minutes. If you have a trailer or Motorhome, you need this!

Came quickly, have only bench tested so far but seems quite easy to set up and calibrate. Connected to both the 9v and a bench 12v supply easily. Paired with both Android ,4.4 and 6.x and up systems. Will put it in my RV this weekend but should be great. Better imho than the other similar choice that only uses button batteries and cost a bit more.

I had initial issues with connecting via the application but it worked the next time I took it out. I emailed support when I had the issue but took a few days to get a response...I was going to return it when it worked later. It seems to reconnect easily now.I think a large ball level is just as easy in the rear view so long as it doesn't freeze. That was why I got this.I turn on the app and use the anderson levelers and never have to get out to check anymore. Way easier than checking every time and getting in and out.

Installed very easily. It is very sensitive, so you need to mount the sensor on a solid flat surface. I mounted mine in the forward basement of my Travel trailer upside down on the ceiling and centered in the storage area. This will protect it from being hit when things are being put in or taken out of storage. I was able to get it to read within 1/2 degree of perfectly level - not bad!Looking forward to seeing how well it all works out this summer during camping season.

Best invention ever! My husband is the envy of everyone around us when setting up our RV at the campground. We have told several people about this leveling app because we love it so much! Easy to use and very accurate. Buy it! You won't be sorry!

So I rarely write reviews. But my experience with this device and with its creator, Joe have been excellent.First off this thing works really well. It connected via blue tooth quickly and easily. Its bluetooth range is actually very good farther than I would expected. The app is simple and easy to use. The device has adjustable sensitivity but it is very accurate and can work in a number of mounting positions once you hit the calibrate button on the app to zero it out.You can run it off a 9volt battery or connect to a 12volt lead and always have it connected. I didnt test how long the 9volt lasts.Joe actually emailed me to make sure everything was working and if I had any questions.I did happen to make a dumb mistake....I was hard wiring the device to my trailer and I assumed without testing that (white=red or +) and (black=black or -).......WRONG.......So I fried the unit.I told Joe what I did and he said no worries. Took back my broken one and sent another out. Was really nice about it and said he even changed the information on his website and instructions to call it out better that trailers tend to switch up color for + and -. This wasnt his fault at all, I should have checked polarity first.There are only two devices on the market that are electronic leveling solutions and only one of those has a bluetooth function but its not really designed for a trailer or RV and is not in a small packaged box. Also this device has extra settings for axle width and distance from device to hitch which helps in sensitivity. Sensitivity can also be adjust so if you want to check while driving you can turn it down.Sure I could just use a level and my wife and I have gotten really good at the process. Still this will be faster and easier and frankly I always want to double check level anyways. :)It really is a cool unit.

This is a GREAT product. Works GREAT and makes set up a 100 times faster. No more keep adjusting. It says 2" you raise it that and you are good to go... Would not have a camper with out it.....
