The only ones i find any good now days and all i use now are the Transpo HD Adjustable VR , i get them on Ebay for 22 bucks CND it says they are made in the US but for that price that is questionable .
I did some research on them. Transpo has a manufacturing plant in Orlando, FL, which is also their headquarters.
Transpo was acquired by WAI in 2004, and operates as a wholly owned subsidiary. WAI is headquartered in PA but has a 100,000 sq ft facility in Shanghai, China.
Their narrative is impressive, but it's impossible to tell which products are built in the US or China.
How long have you had your Transpo VR? How does it adjust?
