Well for me the hair color almost always comes back correct and the hairline shape is always right too. But the ventilation direction has almost always been wrong and the same goes for the base size. Sometimes it's an inch too short, sometimes it's an inch too long. The density can be a bit of pot luck but usually comes back within 10% plus or minus, sometimes spot on.

The best and most relaible thing has always been the delivery time. I have never had a custom piece come back in more than 5 1/2 weeks from payment date to it showing up. It's a very reliable service that way. But when it comes back an inch too short it means waiting a lot longer to get it sorted out. John is very good about working to resolve issues though.

Think of it this way: They are made in China. The Chinese aren't reknowned for exporting highly precise and well made produce. But if our units were made in say America, by American factories we would be paying 5 times the price for them.
