Review on KeySmart Magnetic Keychain Secure Attachment Men's Accessories by Ben Rodriguez

Great product but there was one major flaw which I am deducting a star for. I ordered two packs and the key fobs in the set were reverse polarized so they were not compatible with each other. If you try to connect them, the magnets will repel each other. So I couldn't trade two car keys for a set of house keys with it. I solved this problem by ordering a third in the same package and using it with either of the two packages that matched the polarization. I will give my wife another one for the keys. This is a fairly significant disadvantage since there is a noticeable difference in design between the single and double pack keychains. Logos are printed differently and magnet holder sizes may vary slightly. I haven't contacted support for this issue, so this may have been an isolated case, but. Still, it's worth mentioning. The rest of the keychains are good on their own. The size is nice and small and the magnets hold well. However, they need to standardize the magnetization.
