This product was purchased and installed at the end of Mar this year. Its use is normal residential once a week mowing duties - by June 28 2018 this product was in pieces. Minor wear seen up to this point in that threads became visible and had to be removed in order to prevent snagging but today it peeled apart tearing two chunks out of the belt prior to snapping. Check before and after each use.

negative

I got this for my cousin. Has maybe 4 cuss words in it which I only mention because some parents are very strict. But it is not a big deal to me. Good story. Look forward to buying more.

Ex Output:
positive

I have a Vortex 1-8 Strike Eagle scope and bought this as a cheaper alternative to Vortex's cantilever mount. Since I don't own the Vortex mount, I can't attest to how this compares. I can say though that this mount as worked flawlessly. Strike Eagle mounted nicely and after several trips to the range has held the scope in place, kept zero, and never has loosened. Very happy with purchase.

Ex Output:
positive
