Ever wish you had 4 extra hands to hold a project? Now you! These are the best helping hands available for the price. I finally broke down and bought it after years of using homemade helping hands. And I couldn't be happier. The base is an extremely strong and heavy steel plate with small rubber feet underneath. There are 4 arm attachments, 2 longer and 2 shorter. Each flexible arm has a rubber coated alligator clip and an extremely strong magnet so you can position it exactly where you need it. Worry no more because you only have one hand holding the heavy component because the others won't reach. I've even had arms that fully supported the GPU I was working with - didn't phase it at all. My only complaint is that the flex arms don't flex as precisely as I'd like - they spring a bit when you position them. But if it's a compromise for strength, I agree. I had a friend who borrowed it to paint miniatures and then went and bought it for himself because he liked it so much. hands) is what you need. I wouldn't recommend it for hard drives or other magnetic media. Luckily, the company also offers non-magnetic versions!
