I purchased this product awhile back, and tried to use it immediately to prepare for summer bug season. I had a lot of trouble getting the hose to connect to the sprayer. It looks like there is a defect in the mechanism involving the sprayer. Do not purchase this item until it is fixed or the device is changed, it will simply waste your money. The same device is on several other products, all of which I have had the same issues with. The sprayer head on the Ortho Weed-be-Gone seems to work the best, however. I would just remove it and use it on this one, but they are not compatible.
