I’ve recently been seeing other professional cleaners use sprayers to do large surface areas as it cuts down time and energy. They definitely weren’t wrong, it filled nicely without any spillage due to the wide opening, the pump didn’t have any resistance and once it was ready, unlocking the safety mechanism was straightforward and well made, which is hard to come by as so many are cheaply made and feel flimsy these days, so this was refreshing to experience. Once the pump was ready, the spraying action was smooth and covered a lot more area than the standard trigger bottles. What once took roughly 3-5 minutes of spraying on a heavily built up shower, the sprayer cut time down to 1-2 minutes covering all surfaces with several layers. Delivery time was also highly efficient, even around Christmas. I highly recommend not only the sprayer, but also their trigger bottles as they are all well made.
