Review: works well great product for the - Quick delivery, works well great product for the price Review: Buyer's regret - Well, it sort of does the job, just. Extremely crude and makes using it hard work. I've just sprayed a large grass area and wish I'd hired a decent sprayer as I did last time. The price makes it sadly almost disposable; I'm not intending to chuck it immediately, but really doubt it'll last another couple of uses. It'll certainly not be replaced by the same when it it does fail completely. My wife gave up after five minutes - very wise woman. ## Features - GardMax - 20 Litre - Knapsack Sprayer - Sprayer - Gardening ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079Q96CJC | | Best Sellers Rank | 182,200 in Garden ( See Top 100 in Garden ) 871 in Garden Sprayers | | Customer Reviews | 3.7 3.7 out of 5 stars (22) | | Date First Available | 26 Feb. 2019 | | Manufacturer | HSUKLTD | ## Images ![GardMax® 20 Litre Knapsack Sprayer - Image 1](https://m.media-amazon.com/images/I/31EuvLzGEBL.jpg) ![GardMax® 20 Litre Knapsack Sprayer - Image 2](https://m.media-amazon.com/images/I/318oeSY8qUL.jpg) ![GardMax® 20 Litre Knapsack Sprayer - Image 3](https://m.media-amazon.com/images/I/31G8WrYxqlL.jpg) ![GardMax® 20 Litre Knapsack Sprayer - Image 4](https://m.media-amazon.com/images/I/41WwC6LMWOL.jpg) ## Questions & Answers **Q: Does this have to be assembled ?** A: Yes it does have to be assembled, which would be no problem if you have all the bits. I had one piece missing and they told me to return the whole thing instead of send the missing part. As returning would cost more than the item I decided to keep it and hopefully source the missing part myself. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works well great product for the *by A***R on 27 March 2018* Quick delivery, works well great product for the price ### ⭐⭐ Buyer's regret *by S***B on 28 April 2018* Well, it sort of does the job, just.
