Yes, I bought my 1701987 from Pulsar some time ago. I’m curious about how you measured  the “~310°F”). Is it coming from your
controller display reading, as measured with the controller’s sensor, from an external IR sensor, or some other way?

BTW, I found that at around 275°F, when tilting the unit back about 45° to enable feeding small coupons in, it allows the heat to
escape through the feed slot, causing serious warping of the housing (I just trimmed it back as necessary). I think we are operating
at very near the max temp these housings can withstand. Have you experienced any warpage from overheating the housing?

Interesting comment Roger - I have the two heat model #1701987 from Mybinding (Ebay seller) that "seems" to be the same as the one
from Pulsar - can you confirm the Pulsar is the 1701987 model?

I also have one of the single heat versions currently sold by Mybinding - I've not even taken it from box. I purchased it as a spare
thinking it was the same as the 2 heat model 1987 I had. Ooops - I should have checked closer before purchasing. I do think it will
handle 300F heat, and I do use an external controller that I homebrewed using an ATmega168 chip. I do TT around 310ºF and am very
pleased with the results.

One of these days I do need to drag the new laminator out and test it.
