## Customer Reviews

### ⭐⭐⭐ 







  
  
    Mounting hardware is cumbersome and doesn't work well
  

*by T***J on Reviewed in the United States on September 29, 2011*

I regret buying this product simply because of the mounting hardware designed to keep it on the bike was not very useful for me.  Maybe a defect with my item but it's very difficult to slide the lock on and off the mount and it.  The mounting hardware is also difficult to keep tight onto the bike frame make it loose and sometimes in the way when it moves to either side.After this experience I would prefer a lock that does not latch in the middle so I could more easily manually wrap it around the frame or store it in a bike bag.

### ⭐⭐⭐⭐ 







  
  
    Decent for short stops
  

*by K***R on Reviewed in the United States on February 20, 2012*

I bought this ride for my alternate city bike to use for quick runs.  It's light and easy to wrap around the seat for easy use.  Can't say anything about the lock bracket itself as I am not using it.  I wouldn't trust this lock for anything more than a quick run into a store or locking it somewhere with high visibility.  Could be good for kids as it seems simpler to use than a large u lock.

### ⭐⭐⭐⭐⭐ 







  
  
    Works
  

*by J***J on Reviewed in the United States on July 15, 2011*

It works.Bought 2 of these.Small enough to be able to carry in side pocket of my shorts or in a backpack , easy to set up.Due to small diameter one would be concerned someone with an adequate tool will be able to steal their bike but well you cannot anticipate everything.It is well hidden under the bike seat while biking and does not need a cover or pouch.Works well to secure bikes in the basement of our apartment, or when parking them somewhere in downtown.5 star rating for the product. At least for now. If you want to have more peace of mind go and buy the rigid bicycle lock amde of steel.
