## Product's reviews:
- Not bad - Unfortunately the mounting holes for this receptacle did not match the Arlington DBVS2C-1 Low Profile IN BOX Electrical Box. Otherwise it is a nice product.
- Helpful and good service - Even when I mistakenly ordered the incorrect product, they quickly organised the RMA and paperwork so I could ship right back. Found them very helpful
- Rj600 - .Right box for my project . Got it delivered very quick.
- The right stuff - Worry free order. Came fast and exactly as described. Will use MRO again.
