Shipping took longer than expected

The product itself is fine, but delivery took two weeks. Make sure to order early if you need it for a deadline.

Good hardware, manual could be better

The build quality is solid and the enclosure feels premium. However, the instruction manual is a bit hard to read for beginners.
