This is not the same as the post with the coupon that some people have and some don't. When I tried to get the deal that was posted earlier, I didn't have the coupon, but Amazon showed me a similar item, the one I've linked here.
There is a "save 30% at checkout", so add it to your cart, and the price of the filament dryer should be 83.99 + tax.
Hope this helps you guys that couldn't clip the coupon like me

(Edit) I got it to work. I copied the link above into a different browser that was not signed into my Amazon account. Saw the 30% off offer and added it to my cart. Then logged into Amazon and it honored the discount. No idea why I had to go that route - but so be it.

My Business Prime account had a 20% discount available too, so I purchased two units. One for my work's X1C, the other for my P1S.
I purchased this last week for the same price. It's overall a crappy product, but at $80 I think it's okay if you just use it more like a standard filament dryer, and not as an automated (rH mode) drying system. If you are paying full price, do not buy. Get the Eibos 2 chamber AMS heater [amazon.com] instead for only slightly more.
The Sunlu is way too inaccurate at measuring relative humidity, so the automated rH mode is unusable. rH mode is supposed to kick on automatically if the humidity reaches a threshold you define. Mine always measures 10-30% higher than several other hygrometers I've used as reference. It's not a constant offset error either. So it's not really possible to just set a higher target since the inaccuracy seems almost random.
There's no lock and no gaskets on the lid either, so it's not forming a particularly great seal. There are printable solutions to this.
Setting that aside, the biggest design flaw is the fact that the moisture ventilation is manually operated. The top vents must be manually opened, otherwise the moisture will just stay inside the case. No big deal, except you must close the vents when the drying is done!
There's some automated solutions on Makerworld to the vent issue, but that's a rather annoying design flaw that should have been easy for Sunlu to implement in the design.
For $80 I'm fine just using it in manual mode only and set to run for 24 hours overnight. I do 24 hours that way it won't stop heating before I close the vents. Next morning I close the vents and stop the drying early.
One of the touted benefits, drying while printing is only useful for Nylon in my experience. You definitely do not want to be heating PLA, you will get heat creep and suffer worse print quality or even failed prints and can jam the AMS system. In fact I wouldn't have the heater running on anything except maybe Nylon or PC based filaments, since the risk of jamming the AMS goes up as filaments get softer.
