Review on Enhance Your RV with RV Designer E401 Exterior Hardware by Marquel Floyd

I use these on my road trailer to check the level and they work very well. I had them on two different trailers. I put one on its side and the other on my back. They stick very well and are really difficult to remove. Be aware that once you've placed them on the tag, it will take some effort to get them off. I installed them on my first trailer and they have worked flawlessly for all the years I've had one. I installed them on a new trailer and very quickly one of the fluid filled hoses somehow broke. I suspect that the outside temperature has something to do with it. I contacted the company to inquire about a tube replacement. They said the tubes can be easily removed and they will send a replacement. They actually sent me two new aligners when I only needed one. Great customer service :)
