New 'Vinyl Flat' flattener?

No negative effects that I can hear. The Band's Rock of Ages (2nd LP) is in the flattener now. I'll try and post some short video of before and after.

My first attempt at 5 hours on a severely warped (it was unplayable)new 180 gram LP did not work. It appeared it may have improved somewhat but still pretty warped. So now it's in for a second run....

Based on my understanding from conversation with Vinyl Flat, multiple rounds may be required for more warped records. Especially 180g I would expect.

My problem may be the Pouch. It has been plugged in for about 4 hours, and when I went by just a few minutes ago, I put my hand on it and it was cool. Fiddled with the connection a bit and it started warming up.
It was warm yesterday after I set it up initially, but I moved it to a preferred location and it might have gone cold. So another 4.5 hours as long as it remains working.

The connection on the pouch needs a little fiddling but the third time is a charm. 2nd and 3rd efforts it was on all night, ie 8 hours plus each. Came out flat enough the last time that my Sota Star was able to seal the vacuum lip. I'm not familiar with the LP and it is basic garage/shoe gazer rock so guitar distortion is abundant but nothing seems out of place sound-wise. Success I'd say...
