3 Pack Mini Magnetic Spirit Level 37mm for TV Mounts Etc

Firstly I'm a quality tradesman (yes and I'm English) now that you've wiped up that coffee you just spat out ,, (and I'm an ex squaddie) levels and guns are my thing I was once a regimental marksman. Anyway these are not very good I have 2 that almost match in level and one that defies gravity, I've tested them against a boat level they are not accurate by any stretch but do settle close and are jumpy bubbles I spent considerable time getting them right for what I needed and found my boat level beat them hands down for simply mounting a rifle scope. * beware on a cheap scope I'm not convinced the scope housing and the reticle are alined so simply putting a level on the outer scope my not work. I like accurate really accurate you won't get that with these. I want to be able to shoot off a flys eyebrows at 30yards.What they will do is get you dam close they do sit still after you've trimmed the excess mould plastic off. And the magnets help. These are more suited to leveling a caravan. To level and plumb my new scope reticle I drew a level line and plumb line down range and fixed to that whilst keeping (my boat level) on the rifle to eliminate cant,,, zeroing gets the rest. Don't forget your marksmanship principles!

Needed these to level my scope and they worked a treat. Good price and we'll worth the money.

I bought these to help level my new 3D printer. They work fine but needed sticking down as they are not magnetic at all

Black casing is plastic not metal and metal magnets are very weak. To be expected for the price.

Arrived promptly but all 3 needed trimming and even then none measured level correctly. Not recommended for setting up telescopic sights!

Only one of the three keeps same reading when turned the other way. Expensive for only one working spirit level.

Not accurate with each other or any other independent level indicator. Returned.

Rubbish!
