JBL CristalProfi Filter - Anyone Using?

Doing a little bit of filter research, in the event that I may need to buy a new one. I do have a spare Fluval U2 but it's rather bulky for my little tank. I had the Eheim Pick-Up and Aquaball ones parked as possibilities (Sue mentioned these in the past) but have also read positive reviews for the JBL CristalProfi - has anyone had any experience of it?

That's reassuring; thanks. I've consequently gone ahead and ordered the internal corner one I'd been eyeing up, so fingers crossed it works out as well for me as other JBL products have.
