Replacement parts did not fit, but I to sent it back, and they substituted new replacement arms, and it works great
The products and service received were extraordinary. To have prompt, efficient, friendly, helpful service is such a rarity today, that I fall over when I receive it. But, that is certainly the case. They emailed, called, followed through and delivered everything on time, as requested, made the process EASIER than I anticipated it could ever be, and everything is top quality. I could not be happier to recommend.
longevity is in question for professional use, i would urge you to create something that last longer.
