HTVRONT Auto heat press 2 | unboxing, demo and review

I'm sad its not available in Canada yet...I looked on their website and it is available in the US but not on their Canadian website yet...I think I am going to be in the market for a new press soon as my clam shell press isn't pressing with the same pressure from side to side...I noticed when pressing some neoprene can koozies that when I do 4 at a time, the ones on the left are coming out with the foam flat almost like it never existed yet the ones on the right are fine so I am having to do only 2 at at time and do them on the right half of the press...so I'm not sure if its a heat problem on one side or a pressure issue...my coasters and car coasters are coming out fine, as is the colour on license plates, etc when sublimating which is why I think it might be a pressure issue.
