Totally agree with you but unfortunately there is a dearth of dual battery high power squonkers at a reasonable price point.
You had either the Rage or the Basium - I bought the Basium and it was reasonably good until it stopped reading attys after 14 weeks or so, powerful and great battery life but mine used to get damp in the squonk bottle carrier section regularly, and it seemed to taint my liquids very slightly too as it got older, kinda subtle plasticky taste but maybe that was all part of it dying? Bought a Rage on here and put about 3ml through it before it went right back up for sale, battery door moved every time I picked it up and I canny deal with shit like that. You've got the option of the Topside dual now as well, but after my recent Dovpo foray with the Basium, I'll not bother thanks very much.
