Just got the combo - I suspect this is a newer generation Groovy Pouch as only a couple people here mentioned the heating options: Low, Medium, High. Have had great success on the 5 LPs I tried....and only one orange peel. Sadly it was a Queen debut (embossed cover). Medium at just shy of 2 hours. Then realized that it was from '73 so likely suffering from oil embargo materials. Still perfectly playable, but penultimate tracks on each side have some rumble in the sound floor. I've accumulated some warped cheapo vinyl over the years in the event that I'd find a solution and want some test discs (bunch of Foreigner, Journey, etc). I have a beat up Renaissance Carnegie double LP that has a dish warp on the first LP. Tried two hours at medium: no change. Left overnight on Low (approx. 7 hours) and it came out pretty much dead flat.
