I'm not going to mention or compare any other vaporizers that aren't Flowermates in this review.
I've had the previous iterations of the Flowermate 5.0 series since their launch a year ago. This is definitely my favorite, don't let the three star dissuade you if you're looking for a dead easy device for stealthy situations.
The build quality of the Flowermate Mini is alright, nothing exceptional. The Mini appears to be made of the exactly same materials as the original 5.0, this isn't necessarily bad but the lack of actual improvements in material choice over a year is notable. The unit feels solid and is definitely quite small, for example my credit card/license is wider and taller, obviously not thicker. It's also nice having the option to hide the mouthpiece within the unit and to have it preloaded without worry about herbs escaping.
Burn-ins before usage are definitely recommend as the fresh adhesive from the polymide will be present on the first few runs. At the initial off flavor was gone I was left with a minor flavor of the internals. I will note that the herb does taste nice from the device but that doesn't prevent me from noticing the minute device flavor, which is present when inhaling from the unit cold. Luckily they designed the unit so you can mod it to exclude the device's internals from the airpath.
Heatup is about a minute probably 75 seconds when going for the max temp. The battery hasn't ever been entirely drained for me but I would expect at least 5 sessions from a full charge. The mobile power bank option works very well, I have used it many times to charge my phone, other vaporizers, and MX Performance mouse. If you remove the top lid you can also use the device while charging another, I wouldn't recommend it but the device isn't so clever that it stops these two functions from working simultaneously.
I do find the device to be one of the least efficient units I've used. I am quite often to want to load .05g and expect great hits and feel like I had a good extraction. This is an issue for all Flowermates in my opinion. Its not a big gripe as many users transitioning from combustion to vaporization are already used to consuming more than .1g at a time. However the unit does perform well when it is loaded to a reasonable amount and with the 5 minute timeout you'll be able to get at least 3 separate 5 minute sessions from a single load of .15g.
I normally accidentally leave it on after a session because I am quite quick to forget I have to press the unit 5 times to turn it off after it turns itself off. The unit will not turn off after your session but instead stops heating and you'll have to press and hold the button for 3 seconds to get it to start heating again.
Cleaning is easy and quick, I just qtip with iso the ceramic chamber and soak the mouthpiece is iso followed by the pipe brush to clean it. I would recommend using the brush after every so many sessions to prevent the unit from smelling even worse. The unit does not necessarily smell but the products inside can be smelled through the vents on the sides. I haven't found my car totally reeking of the FM when I leave it in their for a few hours but I can smell it when its loaded and a foot away from me. I imagine someone not always around it would notice it even quicker.
My overall opinion of this vape is positive, for the price I received it for upon release, 85$. I recommend this vaporizer first to users who are primarily interest in having their unit seen in public. Second if they don't want to spend the money for a mid-range priced vaporizer (100-175). Third if they don't want/can't to allocate their time to master a better unit. So all in all, I would say this vaporizer is average (3 star) based on Puffitup's 5 star system. I wouldn't call it good, as there are definitely units in the same price range that in my opinion deliver better and taste better but sacrifice stealth and battery.
Also a mention to PIU for the great shipping speed, and reading my instructions. Always a satisfying experience when dealing with you guys.
