    geniusly!

    Absolutely happy with the Mason 180 lock - soft covering saves bike from scratches, key can't fall out from the lock in open condition + secure, and the most awesome feature for me is that when both parts are connected but the lock is not in closed condition - the lock stays as one! It can be locked with one hand - thats super for me!
    I like that 180 size allows to use lock with different parking stations, in case of narrow tubes on the station I can lock the frame and the back wheel which allows me not to use line if I have to leave my gravel for a short time.
    Thanks to seatylock for good lock, I enjoy using it! Thanks for the answering my questions and fast shipping!
    This is a great lock that you be proud to use!

    Amazing.

    I'm so glad I found Seatylock during my search for the best U-lock. It's sturdy, sleek and so light compared to others currently on the market. This thing is solid AND you can't beat the price for what you're getting. Super happy with my purchase.
