This one's been sturdy and reliable last 3 years.
Link above, button Buy Now, offers replacement parts as well from the manufacture.
I have multiple sprayers for different things, like broad leaf weed killer, Malathion etc...
This is the best of what I have that's operational. Wider base helps with uneven terrain as well.
I may've got this one at Amazon.
As you can see, I scribble what use I have for that particular sprayer on the side as well as the dilution rate.
Bonsai size depends on the job, but easy enough to use a quart or 2 gallons.
If it lasts and is safe to use (some I've had come apart during use), it's a no brainer
over the smaller ones that are like 32-50 oz that don't last. My hand held one I use for misting
is now leaking if pressure remains, and there's no release valve. Found that out last night on our hardwood floor.
