Since I have all these easily charged up M12 batteries, I figured that I should buy a compatible flashlight, because I always have flashlights with dead batteries in them around the garage. I picked this one, because it was the simplest and least expensive. It does what I need it to do, but if I could do it again, I'd pick something else.
I'd say the thing I like least is the magnet. It isn't very strong and it looks just like the on/off button. Both are square, black, and in the middle of the tool. Often, I find myself accidentally pressing it and then frustratingly searching for the real button.
Also, I'm not a big fan of the swivel head. It has nine positions and is very wobbly. I feel like three firm positions would have been sufficient.
Finally, I think the shape could have been thought out better. It's roundish, I guess to comfortably fit the shape of your hand, but when you set it on a shelf above you to shine down, it tends to teeter or roll where it wants to be.
I must say, it's durable, plenty bright, fits comfortably in my hand, and I like that the button only turns it on or off. I find it to be a nuisance, when I press the button of a flashlight expecting it to turn off, but instead it dims multiple times or flashes. I don't care for that annoying feature.
