　　Disadvantages: the material can have better quality

　　In a given market, most people try to do their best on certain things, so a proper balance is appreciated. The backpack weed sprayer is effectively designed to maintain its maximum setting.

　　Although few 2 in 1 knapsack sprayers are much better at generating high pressure, other knapsack sprayers are better at performing tasks that take time. This method can make the general product perform well in most aspects but lack some aspects.

　　It is an ideal product for yards, gardens, orchards, and even small farms. The manual plunger pump can produce a constant 60 PSI in the hands of an experienced gardener. The spray distance is usually 25 feet.

　　However, it is based on the PSI and tilt angle generated by the gardener, and the tilt angle is inconsistent in any model. It is definitely not recommended that the user twitch the handle to fully extend 25 feet. Doing so for a long time will damage the durability of your product for a long time.

　　Spray machine manufacturer's 2 in 1 knapsack sprayer has a European style and design, allowing you to lean on your back or tie the sprayer tightly with your hands, which is very advantageous for mobility. It has a capacity of 4 gallons and a translucent storage tank, allowing you to identify the height of the product remaining in the storage tank. The assembly is very simple because there is no complexity in their construction. Please note that one of the advantages of this knapsack sprayer is that it can cut maintenance time by nearly half.

　　It is equipped with a filter to keep its glove box clean, but it is different from other models. It is just a one-way filter. Therefore, you need to be careful when filling up the water tank. It is especially important to remember that the quality of the remaining materials is not as good as the tank, similar to those materials that are only attached to tanks and rods.
