Does a great job highly visible. Works well with the different fencers that I use in the different pastures. Last a long time. Can't beat it for the price.

Ex Input:
The bench is very nice. I had a few pieces that looked like they were painted over scratches and some of the metal were scratched. I was unsure of some of the screws as you can not tighten it too much or is strips the plastic. wasnt sure on the indents on the metal bars which way they were suppose to go on. the bench broke after sitting on it three times. The glider bar broke. the weld is not very good or sturdy.

Ex Output:
Negative
