Ordered to replace old bubble levels on an RV. Even after reading complaints about the movement of the tubes and the strap not holding. So I siliconized the ends of the tubes to keep them from curling and removed some cheap double sided tape. Replaced the tape with a good 3m. After a few months everything was fine, the tubes weren't moving, but there must be a level leak because the vial is now half the length of the tube and not accurate at all. The other is fine. Get what you pay for I think. Initially 3 stars, now 1.
