I bought one of these for my Husband who loves percolated coffee. As some other reviews have mentioned, the steam does build up underneath the lid at the top, therefore, the most helpful thing to do is hold a tea towel behind it as you refill it up again. This machine doesn't require filters as it has it's own basket which easily lifts out and very easily cleaned. It has a generous 12 cup capacity and it's really fast on percolating the coffee so it's ready to drink too. The hot plate underneath the jug keeps the coffee nice and hot so you can be assured of a hot drink for your next cuppa. We haven't tried out the timer on it yet, simply because it's nice and fast to make the coffee when we get up anyway. It is an excellent valued coffee maker for under $100. We can highly recommend purchasing one of these if you're in the market for a coffee percolator that is fast and efficient.
