On the expensive side but get what you pay for here. They are cheaper than some competitors and for me are the best around. The bags are 100% biodegradable and the material used is clearly high-end. With previous liner bags, I've had problems with them snapping or holes developing when taking them out but no such issues here as the material is thicker and of a great quality. They also smell good and are the perfect size needed. I've been using them for a few months and will carry on doing so as they are the premium product out there. You can also save money with the great deal ChillX offers by bundling together the liner bags at the time you buy the AutoEgg.
