although 4.2 out of 5
it appears the recent model is poorly constructed

BTW OP what brand of Bifen are you using?

A combined use with a leaf blower and fogger attachment:

I bought last year and had some trouble installing the backpack straps on the bottom. There are no instructions for this critical step, but was able to find help on YouTube after making things worse with brute force. I damaged the strap clips and had to return, but they were cool about it.

Learned this the hard way. Never used it once but they would not take it back.

I returned it because the back straps are PURE garbage. I'm sure so many people have spilled chemicals because the straps are so bad.

Leaks after a few uses. End up with puddles of toxic chemicals on the garage floor. You get what you pay for.

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

I've used one of these for over two years. If you're not familiar with pump sprayer use/maintenance, this item will probably be frustrating due lack of intuitive instructions.

If you've used sprayers before, this can be a great solution for few-time use
cases or as a single-chemical sprayer.

The straps are not good but they've worked just fine with the full 4 gallons of liquid in the tank for me during the last 2 years.

If you maintain it correctly, this backpack sprayer can work about as well as a +$80 sprayer.

My HF sprayers always end up leaking on the "wand" part. So I have the poison running down my fingers or dripping on things I don't want to kill

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.

I bought one of these about 5 years ago, and then last year bought a second one for my dad. Absolutely love them, I use them for spraying cybermethrin for wasps/ everything else and glyphosate for unwanted vegetation. The price is considerably More than this $20 one we're looking at, but you can buy the replacement parts if you ever need them.
