I ordered a pair of the ROUND cut for my son and they are SO great! I LOVE them and they are very strong and stay on NO problems at all.  We decided to order the square cut to have another style on hand and my son preferred the square cut. Unfortunately, the earrings that came are NOT the same as the round type...totally different and the magnet is WEAK! I put them on my ear (not big by any means) and they fell right off.  If you get them on your ear JUST right, they stay on for a few minutes, then fall off.  I'm returning these to the seller...will keep looking for some strong, square cuts. Don't waste your money on these, instead buy the round version.
