I had to contact TW to inform them one of the 3 Allen Keys that came with this level did not fit the indicated Allen Screw. “Lisa” at TW responded quickly & arranged the correct size (I hope) to be mailed to me. It’s not arriving until 7-19-19. Luckily I had one the right size in a set I use at my Shop & was able to get it mounted. Have yet to use but mounting it was very easy with instructions provided. Quality seems very good. Figured the recoil of my .308 Win might cause the Picatinny Rail Nount Screws To loosen, I added a couple small drops of Purple Loctite 222 to the threads, tightened them then backed them out & tightened again to insure threads were covered. Instructions state not to over tighten the screws. It’d be nice if instructions provided the correct torque to tighten all the screws to (Rail Mount Screws, Licking Adjustment Screw & the Adjustment Screw) so one does not damage the level. Also the lines on opposite sides of the level bubble are too far away from each end of the bubble causing one to have to look longer to center the bubble between the two lines. I plan to use an extra fine acrylic white pen to make lines closer to the bubble ends so a quick glance will easily show rifle is level or not. Other models that are less expensive ($104 vs $115) have a protective cover for the level bubble which should be added onto this one for its price.

Advantages: Well made, Adjustable w/the Micro Adjustment Screw; folds out if the way; Picatinny Rail Mount for most all Rifkes Or Pistols. Great Customer Service (so far).

Disadvantages: Was sent wrong size Allen Screw, no protective cover for level bubble.Instructions not state torque for tightening Allen Screws (to help prevent over tightening) nor if one should add Loctite or not to any if the screw threads (I had to ask via email after receiving the level).
