I've only had my new case for about two weeks, but so far I am loving it. I had an older Bam case before, and it was quite heavy, to the point where it was hurting my body to carry around. The Gewa case is only 8 pounds, which is less than half the weight of my old case. It is so light and easy to carry around. The backpack straps are comfortable and seem very sturdy as well.
The padding and whatnot in the interior is also movable to get the best fit possible for your instrument, which is nice. I also love that the strap holding the neck of the cello is not velcro, and neither are the bow holders. Velcro wears out over time and isn't very secure. This was an issue I encountered in my old case as well.
Some people have commented that with this case it can be difficult to get the latches to line up and close properly. I have found that if you close it and push the top part of the case together (around the top scroll area) while lifting the case, it helps get the seal to line up which makes closing the case easier. I saw a video of someone doing something similar with a different case and it worked well with this one.
Overall, I love the case and I'm confident that it's going to be protecting my cello for a long time.
10/10 would recommend. Definitely worth the price!
