My first Vamo cost $40 US, the second $30 US. $30 is about 20 pounds. As mods go the Vamo is pretty inexpensive - even at 35 pounds, which is about $50 US. I think the price point of the Vamo has seen a lot of people buy it as a first mod - perhaps you too?
I am wondering if a vendor sold you a version 1 and not a version 2. The version 1 did have issues - the 6 watt bug, and the lack of insulation.
I always check the vendor site for the warranty when I buy mods. My first Vamo is probably nearly out of time on the warranty - I think it was three months, which for a $40 mod is fine with me. Its still going strong. Did you have a warranty with yours? You may be able to get it replaced.
Not knowing what you did, but a problem with pvs in general that comes up is some screw down their attachments too tight. Causes them all sort of hassles.
Yeah its a reasonably priced option for a mod sure, especially with the features. If its has the problems fixed that I had, its probably a fair buy for people, it was those that spoiled it. My first mod was a homemade VV box, for about 15 pounds, which had been nothing but excellent. I sold to a friend hoping the Vamo would be an upgrade, hence my disappointment.
Not sure which version it is, but its a very early one. It does irritate me that e-cig manufacturers seem to release later versions to solve problems thats should have been picked up in the earlier versions in product testing. Not exclusively a vamo problem though.
I think mine is out of warranty now. Someone has kindly offered to repair it for me. I had repaired it myself once but not well enough it seems.
I'm pretty cautious with tightening, though I can't guarantee that I didn't tighten a device too much on an occassion. I definitely don't force them on. The problem could have been caused by the differing sizes of 510 connectors on attys. When I inspected it I was really unimpressed with the post, which in addition to being sunken was loose and wobbly, something I'd noticed before. The sad excuse for the insulating grommet made the situation worse. Partly my fault for not arranging a return/replacement immediately, and fixing it myself.
If this connector has been improved then its probably an acceptable device. Ideally i'd like to get six months plus, use out of something that price, I've got many similarly priced items that have gone a lot longer. I guess I've got much hate for the Vamo, which many seem to enjoy, its just never worked properly for me.
