Bergeon 5402 waterproof tester

Hi All 
Has anyone used the Bergeon 5402 any views it looks like a cheap way to check the waterproof of a watch but maybe a chinese full immersion with pressure guage would be a better option?
Cheers

Never seen that. One problem  is that the crown  won't be tested  if it leaks.

Yes I agree
Cousins uk price is about £68 for this 
So I have ordered a chinese wet tester for only £95 I think it's worth a punt

Many people here including myself have these, work just fine. Do not leave water in it, as will corrode the base of the tank.

Ah yes, I had to epoxy my corroded base, and I'll raise you one: don't use ethanol to clean the cylinder! I had formed the habit of using full-strength ethanol in place of rubbing alcohol, and about 2 seconds after rubbing a bit on the cylinder, huge cracks started forming. 

Turns out that smart people know that acrylic and ethanol don't mix well..

Luckily, I found a local acrylic seller that sold me 1m of matching pipe pretty cheaply, and I managed to replace it. Machining this stuff on my lathe was an absolute nightmare though, since it is incredibly grabby.
