This is the best level for Conduit Pipe Bending.Fits easily in my tool pouch & durable enough to last many years of daily use. Magnets are very strong.

This is a great tool. I have lost a few of them, but always replaced them. For an electrician, this is probably the best torpedo level, excelling even the Klein version. It has spirit levels showing 0 degrees, 30 and 40 degrees for bending offsets, and 90 degrees. (I may be mistaken, but I believe the Klein version only has 0, 45 and 90). It has very strong magnets to hold it to your conduit or strut even as you move it around.

I have been using this level for a couple of months and could not be happier with this level. It is very compact and has incredibly strong magnets. I use this mostly for bending EMT for electrical purposes, and the strong magnet allows this level to only need a small portion of pipe to stick to, where as some levels need the whole magnetic section touching metal to stay attached. Ive dropped this off of ladders a number of times and it is still true and level. You will want to cut off the string it has attached, it just ends up getting in the way.

Best level I own. I carry this in my tool pouch daily and I love the small bubble, it really allows you to be precise. And it's a reputable brand, Greenlee!

I’m a Greenlee fan and I wanted a level that nobody else had since everyone seems to have the same tools on the job site. It’s accurate and gets the job done. My only complaint is the lanyard gets in the way constantly so you might want to remove that first thing. Another thing is the price. I realize now that I was paying for the name, as I didn’t know that if a had searched Amazon a bit more thoroughly, I could have basically got the same exact level for $14 less, but from the brand I presume manufactures levels for Greenlee. The only reason why I knocked a star off was for the price. If the level was manufactured in the USA, I would have been quite alright with the price, even if it ended up costing a little bit more.

This is my 2nd time buying this. I lost the first one at a job site, so I got a Klein level. Not knocking Klein, but I'm my profession (Electrician) everyone around me has the same one... and the Klein one is a little more bulky and heavier. The Greenlee level is slimmer, compact, and in my opinion more accurate than all the other levels. Plus, it's one of a kind. Anyone sees a green level anywhere, my coworkers will be like "that's Jeff's."

So it seems that Greenlee has decided to use deceptive sales practices in selling this product. I've used the Greenlee Mini for years. I mean the true version of L77 level. The one that's actually "Mini" And the one that's made in the USA. That is was built in America made paying the premium price worth it to me. This one that was sent is also labeled L77... but they sent out a longer version... not the one on the Amazon advertised photo, and it's also one that is made in China. This has shady written all over it and I'm very disappointed that a company like Greenlee would try to get away with something like this. It makes you wonder what other "junk" they selling at a premium cost but are trying to substitute under the guise of "Made in the USA"

Title says it all. I've used this for electrical work now for over six years and have no intentions of replacing it anytime soon.

Not many people have this level where I work so it’s nice to easily identify your tools. Magnets are perfect for conduit, I own Klein as well and their magnets are a little too much at times.
