Well done

Had 2 malfunctioning batteries that were almost a year old. I was always too busy to get in contact with FlowZone until the spray season was over. Contacted customer service and they shipped me 2 replacement batteries asap. Well done customer service folks.

Great product!

My experience with Flow Zone 2600mAh

I finally bit the bullet and bought the cyclone 2. It's less than 3 years old. I have only recharged it approximately six times, When I first used it the battery seemed to last along time. recently the sprayer quit abruptly. I recharged it, put it in and upon turning on the sprayer it discharged instantly. Attempted two more times. Isn't the technical claim say over 700 charges, Can't tell you all how I feel about this. The battery will cost over $100. Company has me cajónes If battery life was what it claimed, this would not be an issue.
