Okay, I admit that I haven't been giving my Solo as much love as I had before because of my new E Nano desktop. That being said, I decided to have a "Solo only" (not counting concentrates) day. All findings are strictly anecdotal and need to be taken as such. I should also state that I am not sure what my previous unit's model number was. I do know that it had the older "copper" colored heater base and the smaller air holes. Both that unit and the new one came from PIU's new stock (at the time).
I should also note that my previous unit was less than 3 months old before it died and was sent back to PIU for RMA.
Anyway, having spent the day with the Solo I think I have a better feel for how the two units operate... and from what I see, the new unit does almost everything better. Here's my quantification for the matter:
- My new unit heats up quicker. While its not one of those broken/magic units that go from idle to "7" in 20 seconds, this unit heats up noticeably faster than my old one from a cold start. Point: M1D2
- Unit extracts bowls quicker. I am using the exact same stems that came with my original unit, and am loading them in the same manner. Over the 3 months that I had my previous unit, I would routinely need the full 12 minute timer to extract a bowl to my liking. Sometimes even more, depending on how tight I packed it, the bud, etc... Every time I have packed a bowl in the new M1D2 unit (I've tried 4 different strains) the bowl has been depleted well before the 12 minute mark. Point: M1D2
- Extraction is more efficient. I am also getting a more consistent extraction from this new model. The ABV is a darker brown, and is more even throughout the load. This is in spite of shorter session times. Point: M1D2
- Stock gasket/o-ring seems to be more durable. Now remember, I only have one Solo to compare to this new one, however I distinctly remember my stem becoming noticeable looser after just 1 or 2 sessions. I've been hammering this new one all day and it seems to be rather snug still. And this isnt the first day of use for the Solo either. I've had it for a little while now. Point: M1D2
Now, granted the honeymoon isn't over with this unit yet, and all I can offer are these initial experiences based on less than a week of ownership. However I did want to put this out there for people interested and for prosperity.
