Got my Tobeco this morning, fairly clean, won't take the scrubbing the others did. No need to dink around with it out of the box, juice control is nice, and smooth, for that reason alone it would be my recommendation as to which to purchase. 101vape has the Tobeco for $25, and fast shipping.
That is 3 clones for me, worse of the bunch was easily the most expensive, that being the Robot Tech.
#1 Tobeco: Fit, and Finish very good, no need to change out Oring to prevent lower section flooding/leakage Cleanest of the bunch. Smoothest out of box juice control. Least expensive, cost me $19 shipped from FEEbay.
#2 Red Oring copper 510 pin: available from FasTTech, and Focal.
Fit, and finish very slight edge over the Tobeco, engravings slightly sharper giving it a little better look IMO. Chimney is polished, which is a plus, or minus depending upon your preference. Juice control was fairly smooth out of box, did need to swap JC Oring to stop leaking into lower section (510 area). $22.39 Shipped from FasTTech
#3 Robot Tech: Easily the worse of the 3 clones, also the most expensive. Juice channel holes not properly drilled leading to feed issues (dry hits). Needed the most work to get juice control to turn freely still not nice, and smooth, but honestly sick of fiddling with it. Needed larger Oring to stop leaking into lower section (510 area) easily the worse fit & finish, but still not bad. Most expensive cost me $31 and change with 10% off from Focal. Only real plus side to this atomizer is it has a slightly larger hole in the airflow pin producing a little more open draw.
Final conclusion, over-engineered/hyped atomizer marginally better then an old KFL, mainly due to a little better air flow. Arguably easier to fill, but then I never had any real issues top filling the 3.1, or lite+.
Top 3 favorite Tank Atomizers to date, and I own, most of them.
Erlkonigin nano
Expromizer
Rose
Not really a Cloud Chase, but if I were...
Aqua V2
Billow
Orchid
Personally I'll take the Erlkonigin, very noticeably better flavor, better airflow, simple & quick to fill, build is quite simple once you master it.
Yeah I know it is a mess, but I'm out of room
