## Customer Reviews

### ⭐⭐⭐⭐⭐ Five Stars
*by J***N on 18 June 2016*

Just what I wanted and at a much better price than anywhere else

### ⭐⭐⭐⭐⭐ Excellent
*by R***E on 17 October 2015*

Excellent does exactly what you want it to and has very clear, easy to follow instructions.

### ⭐⭐⭐⭐ Looks great in Sandstone Patio
*by T***M on 10 December 2016*

Overall I'm impressed with the quality and fit of the product. I have used it in a large Indian Sandstone patio and it looks great. The only slight fault I have found is the plastic covers for the lifting handles are very tight and I have managed to break both when removing them (hence 4 stars).
