As for US suppliers, as far as I can determine, everything comes from 3(?) factories in China. I see this as the problem. Does it matter where you buy if the source is the same?
A good part of my frustration comes from the fact that sometimes the hardware is good & reliable but too often not. In other words. the manufacturers could produce a decent product if they wanted to. Back to my comments about QC & manufacturing standards. I would gladly pay a premium & know the product I purchased was reliable.
My current equipment status. Ruyan Direct will refund my money. I have found them to be easy to deal with. I have 2 dead atomizers & 2 extremely weak
batteries. The other 2 atomizers &
batteries seem to be hanging in there. If they last the week, which will make it nearly 3 wks, I will return the failed stuff for replacements, with fingers crossed. If not, I'll go for the refund.
BTW I did consider the 510(?), with the manual switch until I learned a charged battery only lasts 2 hours. This won't work for me.
BTW again. I haven't reached a firm decision about what to do about my nic addiction if my remaining 2 901s fail this week. I've heard bad things, now, about both the gum & lozenges. I also learned that I can roll my own for about $1.10 a pack + a $40 machine, if I decide to go the coffin nail route.
I plan, in any case, to stick around this forum. My hope is that sometime soon, there will be an e-cig that will reliably meet my needs.
