Fair enoughDabnation swindled the original owner/maker by getting his Chinese manufacturer to make the Carta for them.
Should be fine getting from PIU.
Well I don't know, but Focus V the company has not only accepted my serial number as a legit registration for the 3 year warranty they give but are already going to honour the warranty
The plastic ring that screws on the top of chamber has a crack in it - probably from heat expansion
Anyway, I contacted focus v and had told them where I purchased it from and they are happy to replace and create a label for post to them while they send a replacement
So who knows, but appears to be no bad blood between them and no issues with legitimacy with my unit
And piu are free post is why I used them where focus v charged postage
