    Awesome Electric Back-Pack sprayer ! ! ! !
  

*by R***E on Reviewed in the United States 🇺🇸 on February 10, 2018*

I have a pest control company and have used the ESR-18 12v backpack sprayer every working-day for the past 5 years and finally just purchased a new one. I have other electric back-pack sprayers and consider this sprayer to be the best. Since the sprayer is used every day (much more use than the average) I have modified the sprayer by upgrading the pump to a Shurflo 100 PSI. I compensated for the extra weight of the Shurflo pump by swapping out the battery for a Lithium Ion battery. If you are a casual user, this sprayer will work wonderfully completely stock……If you plan to use it every day, you will want to upgrade the pump.******QUESTION FOR SELLER:  When will you make this sprayer available for purchase again? I am interested in buying 3 more units. Thank You:)

    Almost great!
  

*by G***9 on Reviewed in the United States 🇺🇸 on May 24, 2017*

Powerful enough to reach the top of 20 foot fruit trees, holds a charge long enough to spray everything I own and then some. The only reason for knocking off one star is the limited set of spray nozzles-- they need a dedicated nozzle to spray an elliptical pattern at a distance not just a stream spray--you can make the stream nozzle work but I would have preferred an adjustable spray nozzle. None of the salvaged/saved nozzles tips from other defunct sprayers will fit-either size or thread pattern are different.For the price it was an acceptable trade off but another nozzle would have been icing on the cake.
