I have 2 leather loop bands from Moko that are fine. I ordered the black Milanese loop from JETech and returned it, then ordered Moko's Milanese. It was much better.
I do think Moko keeps price low by having no quality control. I have two Moko silicone bands, and one of them had some imperfections.
The other Moko bands were returnable, but not the silicone, so Amazon gave me a refund and didn't require me to send it back.
Clockwork Synergy is my favorite third party band company. I've found bands on their site and on Amazon for $16-$22 which I think is a good price considering the quality and customer support.
