Demao Magnetic Soldering Helping Hands, Third Hand Tools for Soldering, Wire Holders with Flexible Gooseneck Metal Arms for Hobby Welding Crafts(Pack of 2)

These clamps do exactly as described. The hold is firm and having 2 of them is very useful. I would like a version without painted bases. All metal would be better. I cant put these in an oven.

Rey handy and pretty strong magnets. Not real great on round surfaces, but does the job.

I needed some extra arms to support my quadhands soldering station. These were much cheaper than buying genuine ones. They seem fine, with one exception. The magnets are just normal magnets. When you adjust the arms, the base will often break free. On the genuine quad hands, the base doesn't move at all. I pulled the sticker off the bottom and popped out the magnet. I'm going to replace it with a rare earth 18x3mm one. That should fix the issue. Update: I replaced the magnets with 20x5mm rare earth magnets. They fit but stick out a tiny bit. Unfortunately, while better, they are still not as strong as my quadhands arms - by a lot. It is basically OK but irritating. With the information I have now, I'd probably by the genuine thing. Update 2: Success. I learned more about magnets than I really wanted to. I found these N52 Realth Magnets Disc 0.79” x 0.08” 12 Pack magnets and decided to try one more time. They work great and now the arms stick just like the quad hands.

Good value for the money

The gooseneck feature is great, and luckily I had previously bought the bolt-down version of the same thing. The magnets on these are barely adequate to actually hold anything for soldering, so I glued them down. Please keep that in mind before buying these.
