It depends on what you’re looking for. On Trustpilot, they have largely positive reviews but there are enough negative reviews to perhaps make you pause for a second. As cosmetically customized controllers go they’re fine. I wouldn’t count them as the best or worst but they can be a little pricey. For a modded controller they’re good. The mods work as advertised.  But whenever you’re buying an aftermarket product like this you’re taking a risk.
