## Customer Reviews

### ⭐ Two Stars
*by C***H on March 9, 2017*

I purchased two of these... Both has failed..... and it is really difficult to get them replaced since this suppler isn't providing a warranty. The manufacturer is providing the warranty which is really a stressful process..... I want my money back!

### ⭐ Not robust at all.
*by C***E on August 7, 2017*

Bought a Cotek 3500-148 and it failed after about 6 months. It was replaced under warranty, with some protest, and I paid extra to get a SP 4000-148, thinking it would be less stressed. It started to fail after 3 months and now is in a hard fail condition, reporting a DC voltage>62, when the voltage was only 51. Nice-looking stuff but not up to Texas temperatures and humidity.
