This product is far from providing a safe way to tilt a carboy. In fact it is very dangerous because it is made out of a hard and slippery plastic. that can easily slip out from under the carboy and you may loose the carboy and it's content on the floor of your kitchen or garage.I did not use it and will not use it ever.It can be improved by using a softer material instead of hard plastic.I wanted to return it, but I figured it is not worth paying for the shipment.I do not recommend it to anyone and in my opinion it should not be sold as is

Warning: These are made of hard plastic without any grip. If you use a smooth table to transfer these will slip all over the table without something underneath to grip. Using two in the 10 & 2 positions is very stable and works very well at getting as much liquid out of your carboy as possible.
