Equipment is durable and functions smoothly. Delivery was timely. Only reason I’d rate below five stars is due to an issue with the machining of a part. The holes on two parts were not sized correctly to allow alignment for assembly. The only way to bolt the two pieces together was by widening one of the holes with a dremel, which likely has voided any warranty. This wasn’t a huge deal as I had the tools to correct it myself and didn’t care for the hassle. However any person without the tools to correct the issue, would have been unable to assemble the equipment.
