Mark Chase had some issues with his V4TEC
http://www.rebreatherworld.com/bail-...ighlight=v4tec, but from another thread, I understand that they are now resolved.quote]
Mark Chase resolved his issues with his V4Tec by selling it to me!!
I was'nt too impressed with it to be honest.
Too big and heavy for me for to hold in my mouth for any length of time.
It would'nt hold negative test either, which to be honest I knew about before I bought it, but it became frustrating after a while.
Did a couple of dives with it and promptly sold it on eBay (for a bit more than I paid for it

)
I know there are others on here who use the V4Tec and swear by them, but I would'nt use one again, but as Andrew says people make their own choices.
Just my two penneth
Dive safe,
Gary
I know there is now a modification for the V4tec that is standard on their new ones & I believe can be retro fitted to the older ones that resolved the +/- test issues .
I do still have a Kiss Bov with Inspo adapters for sale .I thought it was sold but got messed around by someone on another forum
