I found the cha' ching in the Boba's universe imho. Two words "GP Spheroid". This RBA rocks boba's, and not only does the flavor come in boatloads but it conserves juice unlike a genesis. The flavor is just a notch below a genesis but at the same time cleaner and more efficient. I do find the flavor better here than on other RBA's I have tried and much better than a ViVi Nova with stock coils. The price is high, 85 euros, so I would never say its a must buy. I'm a firm believer that big money is not needed for an enjoyable vape, but this really does perform and can probably be re-sold since they are hard to get.
The build quality is there and its super easy to use. I use a double 3mm silica wick and 32 or 34awg kanthal. I find the gauge just the opposite of a genesis, the thinner the wire the cleaner the flavor it seems on this. If in the market and have the means, pick one up, you won't be sorry. Since I got this 10 days ago I have yet to use a different atty or a juice other than Boba's. Man o man its good.
I just can't get over this thing. It uses poly filler (never gets heated) to hold the juice and wicks transfer the juice downward to the coil. Gravity does the work, no tilting ever, and it NEVER leaks or floods or gives a remotely dry hit (unless out of juice). I just top off morning noon and night, or whenever, takes 10 seconds and yumm. Gravity!! Boba's, no problem at all wicking on this. A 3mm double wick gives 4 3mm wicking points running down to the coil.
The GP Spheroid gets a BBA seal of approval in my book. Don't be scared off by the poly fill, its a genius design.
Anyway gnite all... BOBA'S!!!!!!!!!!!!!!!!!
