They work perfectly. Great for little projects.
Works great in my DYI application! Highly Recommend!
Nice magnets, great for DIY
These are far better than any other magnets out there for aquarium use and I replaced both my fuge lights magnets and my Tunze Comline skimmer magnets. I'd have given them a perfect 5 but the polarity doesn't match my probe holder/ato waterline holder that I previously purchased from Avast so I had to flip the magnet backwards/upside down to replace my broken probe holder magnet.
