## Customer Reviews

### ⭐⭐⭐⭐⭐ Better than expected.
        
*by T***Y on August 26, 2016*

This Lock is much better than I expected.  I read several reviews that were unhappy with it.  Those who were unhappy must have expected the impossible.  Anybody with the ability to read and understand instructions would have no trouble with this unit.I am 72 years old and a one arm amputee but in 2.5 hours it was mounted and working perfectly.  That included drilling and taping 6 holes in steel pipe and gate frame.  Most would drill through and use long bolts but I am a bit of a perfectionist and don't like bolt heads on the outside.Bottom line ...this does exactly what is supposed to do and is very robust in it's design and construction.  I used this with an FM350 opener and there was no issues with timing or delays.  It worked perfectly out of the box.
  

### ⭐⭐⭐⭐⭐ Was pretty easy to install after trip with it to hardware ...
        
*by L***N on March 23, 2016*

Was pretty easy to install after trip with it to hardware store for stainless bolts and U bolt. I had gate close point set right and it worked 1st try. Adds a nice level of additional security to gate.
  

### ⭐⭐⭐⭐⭐ That was great. Instructions were OK
        
*by J***3 on October 6, 2016*

Product arrived day before was due to. That was great. Instructions were OK, so I looked on U-Tube. I leveled the 14 foot gate and drilled the frame and had to notch the farm post. I needed to make a quick run to TSC to pick up bolts, washers and nuts. Running the wire to the control box was simple.  Turned the power back on pressed the remote opener and it worked. How long did it take to do install?  About 3.5 hours. That's with my quick trip to Tractor Supply.  My three dogs don't like the gate lock. They can't push the gate with their nose and get out.
