Purchasing a Senfeng Fiber laser CNC and Laser Welder

Hi all. I'm new here and to Laser Cutting and Welding.

I sold my CNC Plasma and am flying out to LA on (Tuesday 6/8/21) to purchase a SF3015G Senfeng 1500W Laser Cutter and an SF1500HWM 1500W Laser Welder, They are based in China, but have a demo center/showroom in LA.
The price I negotiated includes delivery and installation of both machines as well as 2 days of onsite training. The laser source is Raycus on both.

Does anyone else here have experience with Senfeng?

These are the units I'm getting.
