Well just to keep up to date I have been on with the water tight container on the typhoon tonight.
The body of the container is very heavy and very thick, so I can believe the 10M maximum diving depth that they can take. Not that I would like to try it to be honest!
Apart from some carefull measuring and checking it has went pretty much straight forward. But like others on here I have noticed the slot in the opening seems to be a little on the narrow side. So might prove to be a bit of a squeeze getting all the components in like the tanks etc.
Only had one problem really, in that the 4mm Dye I was using is on the way out, so made making the threads difficult to cut in the top.
But on the whole the container is a far better quality than some others I have bought, where the mould is a bit wonky and the seams are very weak and leaky if not modified. My T class had awfull problems with the drift in the mouldings. Think they had been overused.
The only thing that seems to becoming apparent with the Engel kits is you need to have the correct tools for the job, like anything else I suppose. Now I know most on here will have, but unless you have things like tower drills, dyes and such they might prove to be tricky.
One other thing that helps is an understanding spouse, mine has not yet started the full scale moaning but I am sure its on the way, the whole " I am just going to do a little bit!" and 2 hours later ......
