Worth the price!!

Considering the price this thing, does the job very nicely! The pressure is great. It comes with many different attachments… You can tell that it's made of just hard plastic resin. The only downside I would say is if you happen to drop this sucker while it's completely full it most likely will break. It doesn't feel like the Plastic is all that severely durable if you have an accident with the piece… I'm gonna keep it considering the ease of use and the price point.. filling it was very simple… I was able to spray for bugs and mosquitoes… I used it to kill all the weeds around my property and then spray the entire outside of house with bug killer… Highly recommended product for the price
