IMS Precision 14-16g Filter Basket compatible with Lelit and Ascaso 57mm group head portafilters

Needed a better filter basket for my old Lilit Anna, It had to be 57mm and HERE IT IS. Remarkable improvement in the machine's performance!

So, I’m getting better shots with this basket but IMO I think it’s at least mostly to do with the holes being finer and fewer than on my stock basket (rather than the precision-ness of the holes). Because of this, I needed to grind courser, otherwise my machine would choke. Naturally I’m having less channeling now with the significantly courser grind settings and my shots are tasting better. I really wonder if I had a non-precision basket but that had the same (lesser) amount of flow area holes if it wouldn’t pretty much be the same.

It could be that I have a defective one but I am experiencing two key problems with this product paired with my Lelit Anna 2.1. I am only able to get 10 grams before the puck sticks to the screen2. While brewing, water comes out of the portafilterI have changed the seal in the group head. None of my other baskets leak like this. It just is not sealing unless I really crank it hard (way tighter than I should have to)Anyone having these issues?
