Review on Optimized Magnetic Holder - Perfect for Extra Large Security Needs by Eric Temple

later 4 stars but with the caveat that you have to change the magnets. I bought Taqton from Revain, 2.5 x .50 x .25 - TAQTON Neodymium Bar Magnets, N52, 2½" x ½" x ¼", pack of 2. Strong permanent rare earth magnets. Fridge -, DIY, construction, science, craft and office magnets which is an incredibly strong magnet You will need to sand and trim the plastic box a bit - just cut or sand a small edge and then I have the new magnet with epoxy taped to the holder.I had one of those large keys with electronics on the key itself (Toyota) and need this holder - none of the others will fit.I also used tape to go over where the top of the holder snaps together - just to to ensure that the top is securely attached, I attached it to the frame with a new magnet, the hold was incredibly strong and I think I've solved all the issues in the negative reviews of this product.
