Got my Smok XPro BT50.
This is just a quick review just after I got the BT50 earlier today.... so far, the verdict is still out on it. The width and depth is about what I envisioned... but it's a 1/4" taller than I expected. None of those are anything to complain about... I'm just mentioning it.... For a size comparison for those that have one... it's just a little shorter than an MVP but about the same in the other directions. There are certainly smaller mods available now if you are looking for one of those... I'd say this one is just a shorter but average sized one that uses a single 18650.
The screws for the battery cover... they are hex screws instead of phillips or slotted and they are much longer than they need to be. With the popularity that magnetic closures have... I see no reason for any type of screw especially a hex headed one. With the USB charge option, that will likely not be an issue with many but I would have liked to have been able to switch out batteries quicker or just charge them in my other charger without having to remove the screws.
The buttons... I knew they were rattly... I just didn't know they were RATTLY...
The 510 connector is recessed slightly in a 23mm diameter depression... not even a MM. This won't be an issue with 22m atomizers but could cause connection issues with larger ones. The Hanna style mods have a similar setup... Again, I think this wasn't a very forward thinking design that just brings limitations that could have been avoided. The 510 connection is self adjusting... so that is certainly a plus.
The weight of the device with a battery isn't bad... so not an issue there. It comes in at 176g with an Efest 18650 2500mah Purple battery. My A-Mod ZNA clone with a 18490 1600mah AW battery weighs in at 189g and my Vaporshark DNA 30 with a built in 1300mah battery is 123g.
The BT50 is bluetooth capable. Without enabling the BT, the mod takes a moment to wake up and fire, when the BT is enabled, it fires right away. The bluetooth is what gives the user access to their puff meter info, as well as a vape log. It is also how you can setup a custom firing configuration that allow you to preheat the coil at a higher output and then drop back to a lower one. You have up to 5 settings or I should say stages for the custom config that last a maximum of 12s combined. For my own needs... the custom firing config is all that I could see using of the BT features... You are also unable to use any of these features without an iPhone or Android smartphone. Oh... just found out that if you back out of the Android smartphone app ( Smart BEC ), it closes the app and your mod will turn off the BT a little later... you must keep the app running for this to not happen. So another knock against it and how they've set it up to work.
Would I recommend it to others... maybe would be the most I could say but at this point I'm leaning towards no more. You can get a 50w CDNA style mod for less and I'm uncertain if the BT features could make up for that even with the custom configuration it has. It isn't a bad mod... it just doesn't stand out from others I've seen. Unless you want one or two of the BT options... I'd say save about $10 and go for the M50 model instead if you are set on getting a Smok brand device.
