Review: Strong, many uses but plan your use well - Plan project wisely first. First off, quick delivery, great seller. I may be a little harsh on the review but mainly due for my issues durring use and the seller has a better but more expensive option. Con1- 3m tape will not adhear on felt or fabric for very long mounted on the side of an object. Even with pressure for 1min and left to dry for around 24hrs. The magnet will slide/pull off if shear weight/weight is applied. Using glue with the 3m to try to re-mount did not work since the glue would not cure or hold well on the 3m tape. Like I said, did not work well for my use but the tape method could work on a clean, flat surface and possibly on the side of a flat, clean, non fabric surface. Wear clean gloves when applying the tape to magnet or to surface. Dirt and oils will degrade the glue and will not set or stay in place, so make sure your tape is prefectly lined up with the magnet when applying and applying to surface. Con2- even though it should be well known, these are very hard/brittle magnets. If another magnet hits another or a metal object is pulled into the magnet, it will break and or shatter. use caustion. Better option to these are the magnets with brackets that have pre drilled holes that come with screw. Helps protect the magnet on 3 sides and mounts much better. They are more costly and do require them to be screwed onto location. These are also available through this seller. I would even say, using the backet ones with glue or double sided tape is a better option since the magnet would be more protected from damage. Do not store or place magnets near electronics (tv, cell phone, computer, gaming console) or any type of digital storage device. They will be damaged, erased or destroyed. This is basic practice with just about any magnet, so use caution. Ferrous materials (steel/iron) can and most likely will become magnatized if left on a strong magnet for awhile or if the object is slid off the magnet to many times. Rock/pull off object, dont slide it. (Thus why mounting is important). I tried mounting a few about 1-2in side by side( verticle and horrizonal) to give additional mounting strength but the magnets would attract eachother and the one with the weaker glue would come off and stick to the other. Thankfully they did not break. In summary, they are pretty strong and have many applications, they just did not suit my use perfectly and there are better options for similar uses. Instead of returning mine, I'm sure I will figure out another use for them. Only difficult part will be A- storage and B-removing the tape or de-glueing the tape for storage then re-glueing them. A nice option from the seller would be to provide non drilled brackets to place these in for added protection.
Review: Surprisingly strong magnets that hold up under real use - These magnets are great quality and unbelievably strong. I used one set to hold a sunscreen panel against my front screen door, and it stays put even in windy conditions. Just be careful when handling them because they snap together hard enough to pinch your fingers. Solid product if you need real holding power.
