The SXmini team always has great packaging ..

Snugly tucked in ..

Included were the MQ Class mod, USB-C cable, Warranty Card, and great User's Manual ..

As was always the case with the SXmini Team, the User's Manual was soo good, I decided to scan it up for you guys. MOST other manufacturers should aspire to have manuals this good.

Initial setup ..

Quick start, button sequences, modes, and screen orientation ..

Temp/VT Coil Modes, Smart Curves, and User Programmable Curves ..

Troubleshooting, Specs, and Precautions ..

And finally, the MQ Class ..

Albeit smaller, this one was a show stopper at any angle ..

Closeup of the threaded battery cap, and USB-C charging port ..

The battery cap had a "hump" which was well thought out, and faced towards the battery to prevent excess threading to snug up the battery ..

Clear polarity markings inside the tube ..

Finely CNC'd top plate (and bottom plate), with 510 connection ..

The back had a gorgeously mirrored center stripe with the MQ Class text ..

Single 18650 only ..

Even though it was only a single batt mod, and topped out at 60w, I decided to torture test it at max power using the SteamCrave OG RDTA Aromamizer for DTL at 60w ..

As well as 8-12w using the SteamCrave Classic MTL ..

The display while smaller, actually provided everything you needed, including Batt Reserve, Watts/Volts (in Power Modes), Puff Counter, and Coil Resistance ..

Choosing/Changing Modes ..

Power Curves ..

Exiting Setup, or Powering Down ..

**Testing / Usage*

The majority of my testing was done in Wattage Mode, but I did do some testing using SS316 coils in Temp Mode, and it worked very well. I setup some User Curves, but preferred the "Hard" preset curve (125%-100%) for both DTL, and MTL. Despite running it at full bore (60w) for my DTL tests, it performed very well, and my Molicells lasted about typical for a single 18650 with no issues, until the batteries went dead. MTL also worked very well, and at the much lower testing wattage, the single battery lasted almost for a full day under heavy usage. The smooth feel, and stunning looks were really something, and looked even better in person. The threads on the 510 connection, and battery cap were very smooth, with minor "figit-ing" on the battery cap. The crisp tactile buttons were very clicky and responsive, and the somewhat small display was bright enough to see in direct sunlight. The menu/nav/sequences were fairly intuitive, and I only had to reference the manual once or twice.

**Pros*

* Stunning Looks
* Felt great in the hand
* Clicky tactile buttons
* Bright display
* VV/Wattage/Temp/VT Coil Modes
* No rattles
* Snug battery cap
* User customizable curves
* Puff counter resets when USB-C plugged in (good for tracking puffs per battery charge)

**Cons*

* Single battery, 60w max. (con ??)
* Battery charging port on bottom (might require tank removal first)
* Slightly figit-y batt cap initial threading
* No coin slot on battery cap
* Puff counter resets when USB-C plugged in (could be Pro, if tracking puffs per battery charge)

**Conclusion*

Not only was this a well thought out and implemented mod, it was a show stopper as well. Gorgeous looks (hard to fully capture in photos), and it felt very good in the hand. Being a southpaw, I had zero issues using it, and I tested it in both "Righty", and "Lefty" orientations. About the only REAL complaint would have been the bottom mounted battery charge port, as depending on your tank, might require removing it, before inverting the mod to plug in. This of course would be moot for anyone (like me), who removed the battery for charging in a charger. The puff counter also reset when plugging in the USB-C cable, so for users who DID charge the batt in mod, you would only be able to track puffs per charge. For a single batt mod, it actually fared much better than expected running full bore at 60w for my DTL tests. Obviously quality batteries will yield better results. With coverage up to 24mm, both of my small mid-smaller tanks fit, and looked great on the MQ Class.

The mirrored stripe on the back really set off the mod, and while you could smudge it up a bit, it didn't prove to be a fingerprint magnet. A few times, I had to figit/fiddle with the battery cap to get it started, but other times, it threaded straight away. The small(er) display actually proved to be more than adequate in every day usage, and even in direct sunlight. Nav'ing, and running it was very simple, and after I read the manual, and started using it, I didn't have to keep back referencing it. Heavy dual batt (or more) DTL'ers might scoff at single batt mods, but this one worked pretty damned good at both 60w DTL, and 8-12w MTL. All in, it was a very impressive unit, that covered about all modes that you could want. I only regret that I didn't have any VT Coils to test out the VT Coil Mode, but the stellar Power and Temp operation, didn't leave me wanting. All in, a very well thought out, designed, and machined single batt mod, that worked very well for both DTL, and MTL. If you are looking for a smaller, much more portable MOD that actually does DTL, and MTL, this one, might just work out for you.

Thanks again out to David from SXmini for sending this one out for review, ***and stay tuned for my upcoming review of the Yihi SXmini PureMax 2 !!!!***
