## Customer Reviews

### ⭐⭐⭐⭐⭐ Great purchase
*by D***D on June 8, 2021*

I love this rainbird and use it daily on my back pasture. It's sturdy and covers a lot of ground. I have tried other types of rainbirds but they get plugged up from my well water. This one hasn't plugged up at all and I would highly recommend it.

### ⭐⭐⭐⭐⭐ WELL WORTH THE COST!!!
*by H***E on June 29, 2018*

Quality built sprinkler head and shipment was on time! If you have a large area to cover and want a well built sprinkler this is what you pay for here. This sprinkler covers large areas easily and quietly. Has a high arc water stream that really throws it far. You get what you pay for here and the extra cost is for quality!

### ⭐⭐⭐⭐ nice item
