Question: Does it need to use a flat disc filter?  Why are they being offered to ve with this percolator item.
Document: Nice,small coffee percolator. Simple, easy to use and cleans up quickly. Especially nice if you all you need is 2-3 cups of coffee. Been using it for about a week now -- great!
I purchased this item for my brother because I have one for over 5 years and it is still in great condition. It maintained it's shape after numerous washings by hand and dishwasher. Handle is still firm,  screws remained secured, and glass top never broke. I love this coffee pot and use it every day. Based on my experience, I highly recommend owning one. It is just the right size!
Made wonderful coffee for about seven weeks. BUT then the plastic percolator top broke into two parts. I treated this coffeemaker well -- it was never mistreated, dropped or overheated. Very disappointing that the plastic shatters in less than two months of use.
I ordered this Rapid Brew Stainless Steel Percolator for my husband as a Christmas present. He had been looking for a small coffee pot he could use on his hunting trips. He was really happy that I had found such a nice one. It got really great reviews and you can add our "thumbs up" to that list.
Brews about 1 1/2 mugs of coffee. Because I always use a mug rather than a cup, I should have gotten a larger size. Outside of that, the percolator works fine; however, it isn't made as well as those I remember from my mother's day. The hinge on the lid seems somewhat fragile. My mom's percolators had lids that fit in tightly. They didn't have hinges like this does. The hinge is like that on the stainless creamers you see in restaurants and coffee shops.
It's great. I love it. I can reheat  my coffee anytime. It's good size. Just the filter cannot work better.
Makes a good cup of coffee. I could live without the attached lid, but I wouldnt let that stop you from buying this item
It is a nice coffee maker very small and easy to pack on camping trips and easy to back in my Backpack for long trips in the sierras..I would highly Recommend this Item. ..
Everything's nice. If I had to pick one thing out, I'd say the handle should be better insulated. Always need to grab it with something to avoid a burn. My others aren't like that.Still a great lil' brewer!
I was on a rampage searching for a new way to make coffee. I was sick of my old drip/filter style machine and the coffee was tasting lousy and it never turned itself off. I feared a fire or blowing a circuit breaker or something like that.
Answer: yes
