AG, first of all, thanks for your video. I watched it after I had set up my Silver Dog the other night. So I stripped it down the next morning and cleaned it up.
The wire brush really cleaned up the threads well and a sanding bit knocked of the hard to get burrs.
Thanks for the tip on the oring around the tank. I think that is my biggest gripe with this thing. I just don't get why the two fill holes have no type of sealed connection between the two of them. One, the thing leaks from the fill hole and build up between the underside of the top cap and the removable tank. The first use, I filled up the tank while it was off, leaving a little room for rise because of the displacement from the wick. I didn't not refill on this run, when the tank ran dry, I pulled it to check to see how much juice was lost from the fill hole....A LOT. What a freaking mess. So on top of that, if you use this thing, you loose juice from the fill hole on the tank AND if you refill while the tank is still installed, you can't see when to stop filling until there is juice coming out of the wick hole, and by that time you have probably had juice coming out of the fill hole from around the blunt tip needle, flooding that area even more. The design works, but just plain out baffles me why they would leave that space like that between the two fill holes. I understand it is because of the positive screw needing to make contact with the tank, but IMHO, it is a unfinished design because of that.
I don't know what the update entails, but I did contact the original owner and he is going to forward it on to me.

Hopefully it corrects this.
I'm not a fan of the wick being centered in the device. It reduces vapor production ( comparing it to my ihybrid, orion and MAC ) and if you hold your device at a level'ish plane when vaping ( I'm not talking about tipping, I don't tip my hybrids, I make fat wicks that actually wick; tipping is for beer, not mods

) it gives the wick a chance to run dry while vaping because it is centered in the tank instead of the wick being submerged constantly when at the edge of the tank, even when then tank is starting to run dry.
Also, the use of plastic delrin in the dog seems to be a down fall. Plastic retains juice flavors and since I bought this dog second hand I have been trying to get this sour watermelon flavor out of it with no success. I have tried scolding hot water after stripping it down completely but still it remains. Hopefully, eventually it will wear off and my gandalf won't taste like a sour patch kid anymore.
So, these are just my opinions, I am in no way bashing the designers, so please don't bash me.
Until I get the update, this dog is in timeout.
