The unit is very rugged and works exactly as expected and desired, BUT, the only reason I did not give it 5 stars when it should have received 6 was because it comes with only 3' of hose when it should have at least 6'. This is just unbelievably DUMB as you cannot set the unit on the ground and then get the hose suction end close to where it needs to go, such as the master cylinder reservoir on a pickup truck or say a motorcycle. Instead you have to balance it on top of a pail or a ladder which is a BIG pain with a disaster waiting to happen if a spill occurs. Dumb, dumb, dumb, but hey, they saved on $1 worth of hose. The hose is 4mmx8mm and needs to be heavy wall to work under vacuum. After looking I was able to buy 15' for under $20 on 鶹 but why should I have to do this? Why should you have to do this? I would still buy this unit as it is that good, but be prepared to go shopping for hose if you want it to be stable when being used and truly functional. Just mentally add $15 to the price and the value of your time to deal with this fixable deficiency. I guess we will see if the seller posts a notice that they will be addressing this defect?
