Sorry mate I missed your question.
Yeh I bought the motion tracker kit from him well over 7-8 years ago when he was still located in the UK (although the parcel was indeed sent from Africa).
The main body was a solid piece of resin with most of the details rounded off to obviously make it easier to de-mould for him (these included the barbs that the hoses attach to, making it impossible to attach them). There were numerous large air holes including a 2cm one right on the very top (can't remember the name of the part, it's the part on the very top anyway!) where the resin was poored into. That part would of had to be totally removed and replaced. The general look of the parts gave me the impression that the mould had warped or he hadn't reenforced the mould with a plaster case and the result being the parts were warped.
In all honesty, given the amount of money you spend on the kit, your time and the gear needed to make it pass-able you'd be able to get the deal-deal parts or even a MR motion tracker
I was 14-15 at the time and hadn't found the wonders of forums etc, so when it arrived I assumed the quality of it was what to expect from a private seller and not some big company like airfix etc that I was used too so I didn't complain.
I would highly avoid even thinking about buying from him. You'll regret it, I promise you.
The only good thing to come out it was some extra freebies he threw in that added up to about £40 worth of items, he included to say sorry for taking a while to get it in the post (we're only talking a week). He was also very helpful during the purchase process, even offering a payment plan for me at one stage.
A case of the dog-rough with the smooth.

I hope this helps
