"For years I neglected the amount of water I put in my arenas and my footing was always slick and dangerous. I had different watering systems, but nothing was easy to use or did a good job. That is until I bought my Kiser Water Wagon! My water wagon was built to fit my needs and it doesn't tear up my arena like my old water truck. Not only that, it lays out the water so evenly that my footing is exactly the same in every part of my arena! Don't even hesitate if your looking for a new watering system, buy the Kiser Water Wagon now! It's the easiest and most cost effective way I found to keeping my footing moist!" - Clinton From Texas
"My wife asked me why we had waited for years to purchase this water wagon. I am sure we will get some good use out of the unit before winter. Thanks to ABI for the pointers and advise. My phone call with customer service was well worth my time. I am surprised by the high quality of the product, both the design and manufacturing. As was said in one of the videos on your website "Attention to Details". I have worked in the government aerospace industry and could only wish for such high quality products." - Tom From Massachusetts
