After a day of use and about 50ml of juice used, overall im pretty satisfied with this device so far, though with some caveats. It comes with an extra bottle and tubing, as well as a usb charging cable. The bottle cap uses all my 10ml bottles so replacements shouldn't be an issue.
Quality/build wise, it's a pretty well put together device, the cover magnets are quite strong, and cover stays in place. One thing to note is that if the battery removal pull tab isnt tucked out of the way, the cover won't sit flush. I usually tuck it behind the juice bottle or between the bottle and the battery.
the cover Ergonomically it fits well in the hand especially with the curved side, though squeezing the juice bottle on occasion will cause my palm to hit the up/down button if unlocked will change wattage/temp without me noticing. Size wise, its a little thicker than the geyscano (for comparison) and a tiny bit shorter. The finish is nice, and appears to be pretty durable.
There is button rattle in all 3 buttons, which isn't a dealbreaker, but some may find annoying. Also, the bottle does have a little room to move around...neither plus or minus in my opinion just an observation.
Being a temp control chip, it will ask if this is a new coil or same after changing attys, as i believe is common with temp control devices.
Refilling the juice bottle is a breeze, since its pretty free floating once the cover is removed. The cover itself is a bit awkward to remove at first, though as i'm used to it at this point, no longer an issue. The usb charging option doesnt allow passthrough when plugged in.
The display is a bit dimmer than I'm used to, and may be an issue viewing in direct sunlight. There is no firing delay noticeable to me from when its on standby to pressing the firing button. The ohm reader on it is pretty accurate (is off by -.02 or so from my external readers), when not in temp control mode. The power down feature after 10 minutes of non usage is a little short for me, causing me to have to unlock it (5x fire button press).
The temp control has some things to be desired, though I haven't really used it too much, there seems to be issues with how it functions. Testing dry firing with cotton wicking, it would cause scorching from as low as 240f temp setting, and it appeared the ohm reading was more off than when using kanthal. I wont go too much into detail or testing, unless requested since I'm not a fan of how nickel wire tastes as it is.
A big question mark on this device will be longevity. The main reason for this is both at the top and bottom of the chip housing there are gaps i assume are used for airflow for the chip itself, but if there are any leaks, has the possibility of getting to the chip itself. So far however i haven't noticed any leaks from the 510 assembly thus far, but as it's only been a day of use, will have to keep an eye on it. Also it seems to suction out excess juice at the 510 connection area pretty well, and have only seen minimal overflow juice from both the bottom of my rda's where the rda's connect to the device itself.
