I have a review on the SP2 backpack sprayer that you might want to read, as I recommend this sprayer instead. I picked my Stanley up at Sam's for $45.00, and at 1/3 the price of the SP2 and better design features, I would highly recommend this sprayer above ALL others. You have adjustable pressure settings, you can pump it up sitting on a flat surface if you want. and it goes up to 60psi which means, unless you are spraying the tops of trees, it is more than adequate.

4.0 out of 5 stars good sprayer, August 1, 2008

I have been using this to spray fertilizer on all my plants and fruits (foliar feed) 3-4 gallons once a week for a couple of months. The pumping action is good although it loses pressure quickly so you have to keep at it, but it's not tiring. It could deliver a very strong spray at the highest pressure, more powerful than the 1 gallon handheld sprayers so it gets the job done quicker, plus need to refill every gallon now.

I looked at the solo sprayers some of them do not look like rebuild is easy or even possible. This stanley made by chaplin has all parts you can order for repair and is all listed in the manual.

The only mishap that caused a 4 star instead of 5 is that there was a leak by the hose one day, the hose clamp is plastic and cheap, even when tightened fully it leaked, down the back of my legs! Good thing I was only using harmless organic liquid and not pesticide.. I found a metal screw drive hose clamp in my parts bin and it has been working perfectly. I suggest anyone who buy this to replace the clamp like I do to prevent this problem.

My issue with this sprayer is in the compression fitting where the hose connects with the sprayer wand. It failed after only a couple of hours use. I tried cutting off the flared hose to start over only to run into the same problem again. I'm not one to return things if I can't make them better. I dropped the whole plastic compression fitting idea and went with a brass hose bib and hose clamp. A much smarter way to go in my opinion. No more problems. Stanley should spend the little bit extra on a metal fitting and clamp to alleviate customer dissatisfaction.
