Sadly, this is not a "sprayer" so much as a "dribbler." I followed the instructions and even checked out some stuff on Google to ensure I was doing it correctly -- but no matter what, it just dribbled. Sometimes it dribbled more emphatically than other times, but still. Very messy and I'm not too happy about it, as I was using this for pest control.

Seems to work well. Although, I am a little worried it is losing pressure when I hold it by the handle, when pumped to pressure -- I hear a slight hiss. If I carry it by the strap, the hissing stops. The pressure seems good and it has decent spray. The choice in nozzles is a bonus and it comes with extra o-rings and seals. I might need those, to stop the hissing and pressure loss.

My biggest complaint is that it smelled strongly of some kind of petroleum product (e.g. gasoline). I had to thoroughly wash it, and it still kind of stinks. I worry that I received a used item that someone else had been using to store/spray gasoline. I can't get rid of the smell. I used Dawn dishsoap to cleanse the item -- the soap did not lather on the first scrub. My hands still smell like gasoline after washing and using this sprayer.

I want to buy another for alternate purposes, but I don't think I would buy this sprayer or from this supplier again.

Get's the job done, but the nozzle drips if you pump it up more than a few pumps and the trigger/lever will occasionally gets stuck. Wouldn't recommend for spraying pesticides indoors since you don't want poison dripping in unwanted locations and the lever getting stuck in the "on" position can cause the pesticide to pool while you're trying to get it to stop.

Very poorly assembled, with low quality parts (especially the washers) which prevent airtight seals. The result is that the tank loses pressure within 3 to five seconds making it totally ineffective for any use. I disassembled the sprayer multiple times, but the poor design, and irregular cut wahers just do not fit and thus the air escapes before the sprayer can be put to work.
This problem could have easily been identified before the sprayer was boxed and shipped if a simple pressure test had been done, as the escaping air makes a very audible sound. But the fact that it shipped in this condition suggests no quality control at the assembly point..The other seals allow leaking in the wand so that in the 3 to five seconds of pressure the wand leaks at the connection to the hose.
The sprayer comes with multiple extra washers (an acknowledgement that there is a washer problem), but... none of the washers included fit any of the connections, making them totally worthless. Finally, there is no customer service contact, or customer service information on the box, or inside the box. The sprayer I received simply does not perform, and there was no place to go for help. It was a total waste of money. I will not buy anything from iLOT again based on this experience.

Great product. Used it today to spray weeds with white vinegar, salt and dish soap to terminate weeds. Has multiple spray modes. Easy to use and easy to clean. Very easy directions. Comes with another spray nozzle. Make sure to pump it up max for best spray action.
Recommend it!
