Another vote for the customer service at BesteCig, Beci is great and always quick to answer emails.
I've made 3 orders now totalling 20 BE112 atomizers, 10 batteries, 2 passthroughs and about 200ml of juice.
I've not yet had an atomizer that's lasted longer than a week, great for two or three days then they trail off before giving up the ghost entirely. I'm guessing that this must be the way I vape as going by this thread there are few complaints. In any case they are pretty cheap and i'm treating them as disposable. I've no doubt that Beci would replace them if I pursued it.
I've had the same issues with batteries as others with a bag full of flashing blue and red lights. Brings back memories of a Blues Brothers car chase

. They do last pretty well though and only have a couple that have failed.
As has been mentioned packing is great and I noticed that the last order said 'Vitamins' on the slip

.
I've tried the RY4, Menthol, Cherry and Cola flavours so far. I liked all bar the Cola which was grim to say the least
All things considered i'd say they are good value but I would like to see the atomizers lasting a bit longer.
