Wow! I got my two Dovpo Topside just two days ago. And I was amazed what a wonderful squonker these are. And huge a huge kudos to Brian and the rest of the Dovpo on a huge advancement in squonking. The machining is perfect, the board which I doubted at first until I tried it is wonderful even in TC, and of course top fill.
Today though everything made 180° turn. Shortly after my first refill on my red one, a stream of juice started running down the front side (leaking from the top of the 510). Luckily I caught it before running into something important. And I noticed that I now have to take my RDA off and clean everything every 3ml of juice before it starts running. I checked my black one which I only ran 5ml through, isn't so bad yet. I changed RDAs that runs dry on other squonkers and those does the same thing. No leaks inside so far, but I am surprised that Brian or any beta testers didn't catch this.
The machining and the board itself is still wonderful. A big kudos there. But since it is leaking, the top fill feature is now worthless. I mean if I have to remove my RDA to clean it up, all I have to do is to screw on my 510 refill bottle and fill it that way. And my paper towel budget has now doubled since I got the Dovpo Topside. And my wear and tear on my 510 threads has also doubled.
