ProVent 200 vs 'Generic' Oil Catch Can

I decided to add an Oil Catch Can to my 3.2L i5 Turbo Diesel, initially bought a cheapo from Amazon but ended up getting the Mann ProVent 200 sold as a kit by Western Filters in Australia.
The reason being that the 'Kit' from Amazon had the wrong size fittings and no pipes where the kit from Australia... well had everything.
In this video I decided to compare the two before sending the Amazon one back for a refund.
