My Verdict: Based on my analysis of these two beach shades, I would choose the Solbello over the Shibumi if 8×8′ shade was all I needed. The Solbello is easier to set up, it adjusts to the wind direction, and has optional no-wind tie downs in addition to being significantly less expensive. If I needed the large 150 sq ft shade provided by the Shubimi shade, I would choose it and give up the easier set up and deal with the manual wind direction changes.
