I did just for a second consider stripping it down to have a look inside (I’m a sod for taking things apart!) but once the screwdriver was in my hand, I realised that I just couldn’t do it, I love it too much to risk buggering it up just yet
but I did have a really good look around and I reckon it should be ok. There are two screws on the edge down the visible channels but they are very deep set and are squarely in and well tightened. My bigger concern was the 510 adapter but there is a lot of threads to get past. The connector seals it pretty well and the actual 510 underneath also looks well seated and sealed. It was bone dry in there even after I’ve put a few tank fulls through (there was moisture on the top like in the photo in the review). It certainly looks like it should be ok but the proof will be in the long term use. As I think I’ll be using this for a long while, I’ll update this thread if anything untoward happens!
