Review on Celtic Blu Versatile Bluetooth Speaker with Dual-Secure Bicycle Cage by William Bell

Comes with large and small plastic ties. The big ones broke when I tried to install them. New England winters have grown cold and brittle. I wouldn't trust a small one to hold my speaker. Having bought stainless steel zip ties which cost the same as a cage I am satisfied. The photo was taken in my work chamber where my bike lives from 9 to 5. I put it on the top bar so I can adjust the volume while cycling. Update 5-21, cage broke after about 3 months. Since then I've been using an aluminum frame.
