Conclusion: Have never needed the weights.
Had no problems with too much boost (the camera was always good in the hand, neither too light nor too heavy). In Thailand's waters, for example, it would be my guess for similar ...
It may be that it is different, for example, in the Red Sea and / or with other cameras / underwater housings, but, but for the WP-DC 32 and all other waters the weights in my eyes are completely unnecessary.
And even if you need weights: to such an inflated price?!? For a couple of steel parts (which not even shine so beautiful in real like the suspect product photos can be ?;) and some cheap plastic parts.
Had I still wondered before the holiday, why there is no alternative supplier available for a fairer price. now can imagine why there are no competitors.
As you probably simply does not need the whole, no one has so far even the idea except Canon, a hard sell something;)
