RV Designer E401 Graduated Stick-On Bubble Level - Pack of 2

I use these on my travel trailer to check that it is level, and they work very well. I have actually had these on two different trailers. I place one on the side and the other on the rear. They adhere very well and are actually difficult to remove. Understand that once you put them on to the trailer, it is going to take some effort to get them off. On my 1st trailer I installed these and they worked flawlessly for the years that I had it. On the new trailer, I installed them and very quickly one of the fluid filled tubes broke somehow. I suspect the temperatures outside had something to do with it. I contacted the company to inquire about a replacement tube. They said that the tubes are easily removed and they would send me a replacement. They actually sent me two new levelers when I only needed one. Great customer service :)

The quality of the plastic is a bit nasty but the product is accurate and does the job. I added a couple of dabs of clear RTV sealant on either end of the glass vial to keep it from falling out as it's very loose. The liquid changes colour after a few weeks. It's no longer green but it's still easy enough to see the bubble. Would I recommend this product, no I wouldn't. It does the job but there are better products out there.I have since bought a "bullseye level" which I find more robust and practical for my needs. You do need a horizontal surface for a bullseye, which I have.

I added this to out rv. It works well and is accurate. The only issue is the glue. I tried using it with just the adhesive and it worked for a while but when the temp outside hit 100 it started to slide and I had to add screws. Still a good product

I installedVery easy to useOne week later the one on side of trailer was busted and liquid had leaked outIt might have been because this one was on west side in the sunI ordered another setWill see if lasts longer

I purchased three (3) sets of these and am in the process of purchasing another. I will remove the glass tubes and only put them in when I need to park my travel trailer. For the remainder of the time, I will leave the glass bubble level in the camper or in my house so they do not keep breaking on me.With all of the problems these bubble level's have, it would be nice to be able to purchase spare glass bubble balance tubes in bulk and just keep replacing them when they break.....which seems to happen frequently and in a very short period of time.PROS:These really do work GREAT!!!VERY fast an easy to level my travel trailer using these.CONS:POORLY MADELOW/NO QUALITY - for the glass bubble level itselfTHEY DO NOT HOLD UP AT ALL (when mounted on the OUTSIDE of a travel trailer!!) - The sun heats up the bubble tubes and they break - They can vibrate out when the travel trailer is being towedNEED TO REPLACE OFTEN

I got this for my camper which did not have any levels on it. Easy to apply and has worked well now for 3 years. Something to remember for those who get ahead of themselves like I do... Remember to confirm it is level before attaching the level as "level". I caught myself right before I attached the level.... lol

I used this set to add onto my camper. Initially I had trouble getting them to stick and not slide around once vertical but ended up being fine. Then in the middle of summer when it was very hot, and it became too much and the vile exploded- It was the one on the front of the camper getting beat down with sun everyday. I will go with a different set for next season!

I used a spirit level to make sure I mounted these accurately, one in the middle of the back of our camper and one on the side. If the bubble is on center, it's level. If not, the bubble will float to the high side. Count how many marks off center it is. You need that many leveling blocks or 1 inch boards under the wheel on the opposite (low) side. Read the same way for leveling front -to-back. Popular video streaming websites have excellent videos demonstrating the process.These leveling guides are accurate. The marks accurately show how many leveling blocks you will need. I think the curved design helps keep the bubble from getting "stuck" at the wrong spot. They are better than cheaper ones we put in another trailer, and they still aren't expensive.

Super

Fast shipping and they worked well to level camper

These come as a pair and both units were in disrepair. I had to glue the glass bubble lens back into place. Mounting was easy and they worked well after installation. However, the glass in one unit broke after a hail storm. Not very durable.

Perfect solution for levelling our travel trailer. We have two sets on the trailer so we can view level from either side of the trailer.
