GST Artificial Turf falls apart in AZ sun!
This is the 2nd time Turf is braking off at the base in less than 5 years!
Hopefully 3rd install will be successful!
1. May 2015 - Syn-Turf Artificial grass installed.
2. Spring 2017-Turf broke down and with several calls replaced due to inferior product.
*Rep from Syn-Turf did inform me that the UV protection to their turf was manufactured incorrectly.
When replaced, without my knowledge or consent Syn-Turf replaced with exact same materials that they consider inferior. I now know about the 2017 replacement from GST rep upon 2020 inspection.
3. Winter 2020 - Syn-Turf grass is falling apart again.
Already made several contacts with this company with no resolution at this point.
