    • Good value for its price point!
Bubble is a bit difficult to see in low light due to the dark liquid in the vial. Overall it was well worth the money.
Reviewed in the United States on December 18, 2023 by Pellets damaged from shipping. Should have been shipped in a box rather than an envelope.
    • Works as it should
Easy to install. Doesnt take up much space. Surprisingly it is level. Seems to be well made. No issues.

    • Seems decent for the money.
Nothing fancy but does the job. Fits on the last section of my pic rail right where I wanted it. Easy to come my scope a and see it. Helping in leveling the scope when I mounted it. I even verified it with the ones I use for mounting scopes, appears to be spot on.

    • Works as it should and seems well-made.
Works as it should and seems well-made. I'm not a Monstrum fan because Adam ate scopes that I bought, six had defective Parallex adjustment. I ended up buying an Arken scope and will avoid any Monstrum optical products

    • Nice
Low profile, accurate. Looks good.

    • Meh
First off, great service by Monstrum - no complaints there. The level is very visible and was accurate. The machining was very nice and the finish was very even. The hardware is cheap, as expected. What was uninspiring was the level itself was held in place by some sort of rubber cement which had bubbled at the surface - maybe due to heat in storage, I don't know. Might not have affected function in the long term, though I had my doubts about the hardware too, so I returned it, no problem. Bottom line: it's typical Chinese quality. I'd feel fine putting it on an airsoft gun or a budget build, but nothing that's going to see any real use. If you want a decent level at a low price, this exists, but it's also cheaper directly off Monstrum's website. ... show more

    • A must-have for long range shooters
I have one of these mounted on each of my airguns. The low profile allows them to be mounted behind your scope and allows them to be easily visible with a quick glance when your rifle is shouldered. This is NOT the case when you try to use one of those levels that mount on your scope tube, where you have to find your target through the scope, move your head to the left or right to look at the level, adjust your cant so the gun so it's level, then try not to move while you position your had back to look through the scope again. ... show more

    • Excellent Solution
An excellent and economical solution for the common problem of trying to level your scope on uneven surfaces.
