Well, not as well made as the version without the "Medium" switch option. It's a strong magnet and works well. But I have no idea why or why it costs more. The one with no switch mark in the middle is twice as strong as it has an extra steel plate on both sides and the magnet is stronger and somehow cheaper. I only ordered this version because the other one was out of stock at the time. You can't go wrong with this brand, but they seem to cut costs.
