Review: 👍 - 👌
Review: Well designed and made. Comfortable to wear, easy to put on if lifted onto a table first. Spent a long time looking at reviews of various alternatives. Was a little unsure as this is a USA item incurring tax and import costs but still cheaper than nearest alternative. However, be aware designed for USA mains voltage so need to get a voltage adaptor for charger. Used twice for total of two hours without need of recharge. Bought to replace a hand pumped backpack after giving myself golfer's elbow weedkilling a two acre field. Very glad I did - so much easier and more comfortable

## Questions & Answers

**Q: Just received and used it today, it's great but can the pressure be adjusted down? It's very powerful and atomizing the spray so I'm getting drift**
A: Adjust the nozzle or put different nozzle on. Atomizing is preferred for some tree or shrub spraying, but you need to adjust the nozzle. Good pressure is great.

**Q: What all brand batteries work in it? Whats the biggest battery compatible?**
A: Takes the same battery as the Ortho Sprayer.

**Q: Does anyone else have a problem with having 4 gallons of product but tbe sprayer will only spray 3 gsllons and won't spray the last gallon ?**
A: I have the same issue.  I believe it's because the internal pick up tube is too high i also need to see if i can have my harness replaced either way still lasts me about 2 house treatments maybe 3 depending on square footage.  I'm actually looking to order a second one as mine is finally a year old.  Still works after the abuse of arizona residential services.

**Q: ¿Trae cargador para la bateria?**
A: Si, trae cargador para la bateria. Gracias

*by L***. on 13 May 2025*

This is such a good product. I bought it in 2022 and in 2025 it still works perfectly. The battery lasts forever it seems without a charge and I’m so happy with this product that I am buying a second one. I use it for watering my gardens and then I also use it for spraying fruit trees. I find it easier to water the garden with this rather than carrying heavy water cans and walking up and down the rows because it’s just easier for me as an older lady to carry the weight on my back rather than carrying the weight of the water on my joints and wrist and shoulders, etc. 10/10 would recommend.
