Although this pump is smaller it works great for the value. I used it on the farm to spray fence rolls and it can reach over 10 feet of stream. We are very please

positive

I had problem with the 2 screen protectors, any of them paste well on the screen. Very disappointing because I also bought the complete screen protection and I hope not happening the same thing...

Ex Output:
negative

These are great looking jackets that will keep a dog warm, BUT they run extremely small and are poorly made. I've had the stitching come apart on two of these in less than two months. Save yourself the trouble and just find another product.

negative
