The middle gas out was solid no gas could come out. I had to drill it out for it to work.

The built in pump would cease working while filling and when releasing air, but worse was the fact that the bed sunk in towards the middle - regardless of how much air was inserted.  To stay on either side of the bed, you'd have to hang on to the side.  I returned this bed the very next day.

The first grate delivered had been broken in transport.  The second grate is fine; however, the legs are too short to fit over the gas line that is used to start the fires.  In order to make this grate work, we need to place the legs on flat stones.

Gas line metal inlets smooth and do not hold line tight, prime bulb leaks gas into carb and never fills with fuel

Never functioned, the connector never allowed gas through. We could not find a replacement that fit and now cannot access the company. Very disappointed.

I put gas in the no-spill can. When I tried to pour gasoline into my snow blower, it spilled
gasoline all over the snow blower. I tried to tighten the black screw top. It still leaked.
So I thought I better transfer the gasoline back to the old gas can. I could NOT get
the black screw top off. That meant in the future I could never refill this marvelous
gas can. I tried to pour the gasoline into the old can using the plastic tube which is
regulated by a push button. The gasoline would not come out. I HATE THIS GAS CAN.

I loved this when it worked.  We have had leaking CO2 seals.  None of the gun shops locally want anything to do with it, even the one I bought it from, said that I had to go back to the manufacturer.

The videos on Youtube suggesting using Plumber's tape were great, but the remedy did not work.

Umarex need to sort their product support out and produce a gun that can cope with a range of CO2 bulbs without failing.

Be warned.

The carburetor was an exact fit for the old carburetor, however, after I installed it the engine would not start. So I did some troubleshooting to find out if we were getting fuel to the carburetor. The float was hanging down which should let fuel run into the bowl  no fuel at this point. The gas lines were fine. I decided to remove the gas cap from the fuel tank and I blew air into the tank. All of sudden gas starting pouring past the float. There was some type of obstruction keeping the fuel from running. I replaced the float bowl pulled the cord twice and the engine was running fine.

Tells me to go get gas when its low. How does a little inexpensive item like this fail. Had to remove gastank to install. Glad my automaker doesn't build anything that needs to be reliable......like a plane or rocket.

The only thing this could use is alittle nonstick spray on the middle part so the plastic doesnt rub against each other. Thats what i used to fix the problem.

I bought 4 cans of Dust-Off Compressed Gas Duster. I received the 4 cans shrink wrapped together. When I removed the shrink wrapping I discovered that only 3 cans had gas in them. One was completely empty.

Not sure if it is the coupler or the valve but the low pressure side wasn't letting me get a vacuum or add refrigerant

seemed fine when I opened it up but leaked gas all over the place after hooking it up & wouldn't allow it to run properly. Must have been machined wrong because I got another one from the store & it worked perfectly

Gas will not flow through the gauge.  Grill works fine when the gauge is taken out, but apparently this gauge is defective and blocks all flow.

I tried to remove gasoline from my snowblower tank and couldn't maintain a continuous flow to siphon 'all' of the gas out of the tank.  It doesn't work for small amounts of gas in the bottom of the tank.  I'm going to try Terapump rotary manual drum pump which has good reviews.

I was unable to put any gas in my truck,  I installed the Canister Solenoid valve in let than 15 minute,
When I took my old one off there was water in the hose to the filter,  I couldn't get my old filter out from the are Chevy put it, so I left it in place.  I just took he new filter and pushed it beside the old on and used tie wires to hold everything in place,  took about 15 minutes.

While it is made with great solid material, the part hold middle came off only after few try. It was not built in deep enough. Very disappointed because I am a big fan of Volatile.
