### ⭐⭐⭐⭐⭐ Its easy to use and seems real sturdy
*by C***. on December 13, 2017*

I live in a sketch neighborhood in DC and bikes get stolen all the time. In my new place I cant physical bring up my bike to my apartment due to the narrow stairs and low ceilings. So I bought this to go around a large wooden pillar and I also use a U lock for the back tire and frame. And knock on wood, no one has attempted to steal the bike in 3 months since I got this. Its easy to use and seems real sturdy. I like it and would definitely recommend.
