Question: I want to use one of these to warm up filtered water for sinus rinses upstairs.  How long does it take to warm up?
Document: It's pretty much like another one I have and that's fine with me. These things just don't get real hot, probably for safety reasons, but if you have a cup of hot coffee or tea and you put it on, it will keep it warm throughout the entire drinking of your beverage (hotter towards the bottom cause most of the liquid is gone), even if you take a while to drink it, which I do. This one is attractive so I use it in my office.
This warmer has performed admirably under strange circumstances. I use it to warm shaving cream and keep it warm throughout my shave. It's a pretty unorthodox use, but for my purposes I use a large soup cup, warm it thoroughly under hot water inside and out, and set it on the warmer. I then put my cream and hot water in it and lather it up. By the time I get to shaving, the stuff is even hotter than it started.
This does a great job of keeping your beverage comfortably warm if you take the following into consideration. First and possibly obviously you do need to start with hot liquid, it can't heat up cold tea! Also the type of mug you use makes a big difference. I have a tall latte style mug, narrower at the base than at the top and with that mug the beverage is lukewarm at best.
This warmer isn't all that warm, but I find that if I turn it on and let it get hot before I put my coffee on it *and* use a lid on my coffee cup, it works pretty well. It's also good to use a wide mug that's as flat as possible on the bottom, so you can take advantage of the whole heated area.I didn't have a mug with a lid, so I use a glass lid from a trinket box and that works fine.
Yes, I know that's not grammatically correct, but it's still true. You want a mug warmer that's easy to use, fits large mugs, and isn't ugly? You're looking at it.See, I've got this big-bottomed mug that I like to use and most warmers are tiny. Doll-sized. And wimpy. Not this one. Oh, no.
As others have said, this is the best one since the Dazey 25 watt is no longer available. This one is about 2 years old and this week the plastic broke on the switch element leaving wires exposed. It no longer works, which is fine since I wouldn't want to use it with exposed wires. But I am buying another one today because, like I said, it's the best I can fine currently.
Another trick I found and wanted to share, it's a very simple one just that it didn't strike me before, that if I keep it closed with a lid it works even better. I have this coffee warmer by the window. Even during winter with the lid on, the coffee stays perfectly warm through out the day, and since the water vapor stays inside, the coffee doesn't get concentrated, and stays fresh throughout.
I use this for tea and coffee at work. I am frequently away from my desk and usually returned to cold coffee. Not now. This kept my tea warm for about 6 hours today. The "on" light is a bit dim on the front, so be careful that you remember to turn it off. The on/off switch is on the cord about an inch from the base and is convenient as long as you keep your cup an inch or more from the edge of your desk.
I previously had revewied this product. It had arrived late and a bit defective but it worked great. Low and behold, and much to my suprise, the company had read my review and within days, sent a replacement with their apologies. This one was perfect and I use it all day long. Keeps my coffee hot, hot, hot. I am bowled over by a company who cares so much that they read their own customers' reviews and act upon any negatives. They get a TEN in my book.
The cord is about 3.5' long.9. The bottom of the unit has plastic feet, as mentioned in another review, but they are not going to damage your furniture. If you're that paranoid, you can buy felt stickies from CVS or any hardware store and voila.Bottom line: If you want hot coffee and you're not going to be setting this unit down on a paper back book or a pile of matches or something, this is for you.
Answer: Once you turn it on it gets hot "fast." Just make sure that whatever liquid you put on it, is already hot. It will not heat anything up. It's designed to keep the liquid at the temperature it is when you set it on the warmer. It keeps your liquid from cooling off! Hope that helps?By the way, my wife and I love these things. I got tired of rewarming my coffee three to four times in the microwave during these cold winter months in Michigan...
