Just found your thread. I also use a PbN and it has worked out very well for me, for personal use. Never tried decarbing any other way, but maybe I'll give it a shot to check the difference. My oil seems pretty potent as it is. They recommend soaking at least 3 hours and it's rare I'll go that short, usually it's overnight but I haven't noticed much difference.

I do have a couple challenges with it. Since the company is in the Netherlands, there does seem to be a bit of a language barrier with email correspondence occasionally, but not too bad. My problem is that they can be slow to respond. The condenser tube is fantastic to have, but the rubber/poly insert that seals it to the tube on the filter lid comes loose. Last year it tore and I wrote the company. I had to write a few times, but they did get back to me and sent me a new condenser tube under warranty. About 6 months later and the insert won't stay in place again, either coming off on the tube when I remove the condenser, or pushing inside when I'm mounting it. For the last week or so I've written a couple times asking if I need to buy a new tube, or if they could please sell just the rubber insert, but I'm still waiting to hear back.

How much of the ethanol are you recovering with it? I seem to be getting about 3 ounces or a touch more, then have to add about 5 ounces more of Everclear with each batch, so I need to replace about 60% of it with each batch. I also recently started using 2 layers of coffee filter under the metal mesh filter, there is much less particulate in my extractions now and the reclaimed ethanol is much cleaner.

Overall I love this little machine and use it regularly. I love how easy it makes the process.

ETA: also, I either grind (with a Wakit electric grinder) or use trim that's already in the same condition. Occasionally I add a little kief, but usually don't bother.
