HF has their backpack sprayer on sale. Normal price $30, typically $20 before they phased out coupons. Now you gotta wait for sales to buy at coupon price so... Here it is.

I use mine to spray Bifen to kill mosquitos.

reviews are pretty bad
cannot return either
Leaks after a few uses. End up with puddles of toxic chemicals on the garage floor. You get what you pay for.

Quote from Rawimpact :
Bought it for Biden 7.9% compare and save. It's uncomfortable to wear and the strap hardware is garbage. Plastic clips one side broke so I had to tie it. I wouldn't get this again tbh

But I recommend bifen 7.9 from Amazon to anyone who has insect issues

I bought a gallon of bifen IT from domyown.com and it came to around $52.30 with free shipping. Amazon doesn't have a gallon size of compare n save and I couldn't find anywhere cheaper than $52

I have had mine for about 4 years and it still works like new. I only use it once a year though.

I spray Bifen around the house. Last year the mosquitos ruled the skies here in southern California. Spraying didn't do a thing against the little shits! Does a lot to keep wasp from nesting. So far, mosquitos haven't invaded this year. Fingers crossed.

For what it's worth I recently bought the Ryobi cordless 4 gallon backpack sprayer from DirectToolsOutlet and it's worth every penny. No more pumping. Just turn it on and hit the trigger.

I had purchased one about 2 years ago. THE MOST WORTHLESS P.O.S. AT H.F.!
It leaked everywhere. Shoulder straps are a joke. Very poor design.

I use this sprayer with Biden XTS for the past several years here in CT. I spray the perimeter of the house and property, mostly for ticks. I've had no issues with the sprayer (a. LOT easier than using one of the handheld models) and the XTS seems to be doing its job well although I don't have objective evidence of that. It's certainly substantially cheaper than big box insecticide, I'll probably never go through the bottle of concentrate I bought!

Quote from sportsman10 :
Products like these must be leaked tested with water before use. No entry level pump sprayers ships with the connections torqued properly - more so with plastic fittings.

I bought a top-of-the line grill and still had to perform a gas leak test before use. It's part of owning products that utilize liquids or gases, regardless of how much you pay for them.
My hubbie had Roundup leaking all over his back from one of these backpack sprayers. If you have evil chemicals, I would avoid these cheaper backpack sprayers. Not worth the risk. The skin is our biggest organ and absorbs this crap.

A simple leak test with water solves this issue completely.
