Review: Easy to use and strong. - Works great for fitting up pieces to be welded. Very strong and I love that you can turn it on and off.
Review: I Have a Magnet Problem - Not sure what it is about magnets, but I sure like them. I'm sure it has something to do with their ability to simplify problem solving. These switchable magnets are some of my favorites. Not only do they work really well for squaring up materials, but they perfect for jig making. I have several woodworking and metalworking jigs that require the use of thee magnets, and with their threaded holes, there are many more things I'm able to do with them. as far as hold strength, I'm not quite sure they have as much holding power as they tout, but they have plenty of holding power to keep my jigs stationary.

### ⭐⭐⭐⭐⭐ The ability to turn of the magnetic field makes them easy to clean
*by K***R on August 2, 2016*

I work as a welder in a small fab shop, and I have found the magswitch products indispensable for my work. I purchased both the 165 and the 400, and use them routinely for set up work. The 400 is too strong and creates too much of a field to weld near, so it is used primarily to stablize pieces a couple of feet from where I'm running a bead. The 165 can be used in fairly close proximity to the weld area, as the field is not as strong. These models are not designed for high heat applications so I have to be careful how close they are to the bead, and how much heat I'm running. I usually work with thin wall square tubing so it's not that much of an issue as the heat isn't cranked up that high. I do a lot of metal cutting and grinding as well, and they help hold pieces when clamps are not possible or effective. The ability to turn of the magnetic field makes them easy to clean. They aren't cheap, but if you work with metal on a daily basis, they are worth the money. Great product!
