The Citizen CB5009-55E is a high-performance, professional-grade aviation timepiece belonging to the world-renowned Promaster Sky Collection. Meticulously engineered within an authoritative 45.9 mm stainless steel case and paired with an integrated solid steel link bracelet, this model features a uniform charcoal grey ion-plated (IP) finish. This protective coating delivers a rugged, tactical frame, beautifully contrasted by a striking, deep maroon ion-plated slide-rule bezel ring. The primary visual anchor is its detailed multi-dial matte black face, which hosts an intricate series of calculations scales tailored for flight navigation, accented sharply by high-contrast white tracking numerals and oversized luminous sword hands.Powering this advanced aviation platform is Citizen's specialized in-house Eco-Drive Calibre E660 movement, an intelligent light-powered engine optimized with global radio-controlled atomic timekeeping. This allows the module to capture automatic calibration signals across four primary international regions—North America, Europe, China, and Japan—ensuring absolute precision that never drifts over time. Converting any natural or artificial light source into endless operational energy, it completely eliminates battery replacements. Protected beneath a premium, scratch-resistant sapphire crystal and balanced at a solid 13.7 mm thickness, the armored framework accommodates an advanced utility software suite: a 1-second split chronograph, an independent daily alarm, a 24-hour sub-register tracking window, and a full perpetual calendar that auto-adjusts for leap years. Completed with a professional-grade 200-meter water resistance rating and managed by a secure screw-down crown with protective side walls, this high-flying reference bridges industrial aviation technology with uncompromising tool-watch durability.

Overall good frother
Color: Black
Bought the Maestri and the Zulay frother to test which one is better since both had good reviews. Returned the Zulay (see Zulay review) and kept the Maestri. Been using it for a few days now and works well. Mixes chai and hot chocolate well. It has one speed that is a good speed to mix, but not so fast that it causes the drink to spill over the top as long as the cup is filled to about 80% full. Because I tend to use the tall 20 oz Contigo autoseal cups, it could benefit from offering longer attachments to reach the bottom of the cup (note: that I did not find any company that offers longer attachment arms).

LOVE this frother and the creamy results!
Color: Black
I LOVE this gadget! And I'm not a gadget person. Since I got it a few days ago, I've switched from using my Nespresso coffee maker, which uses pods and which I really like, to using Starbucks instant coffee packets (cheaper and more environmentally friendly than pods). I put a packet of the coffee and two packets of Equal in a cup, add half and half, then use this frother to mix them. Within a few seconds -- no more than 5, if that -- I have a thick mound of creamy froth. Then I had the water to finish making the coffee. Fantastic. This thing is so easy and fun to use. This is not the cheapest frother available. I wanted a rechargeable unit that has sufficient power to make nice, creamy froth. Also, I didn't want to spend $10 and have the thing break and have to replace it. Reviews suggest the cheaper ones are fine if you don't regularly use a frother. I never used one before and didn't really think I would use it very often. But I like it so much, I've been using it twice a day. Also, I first saw one in use while traveling in India. Another guest at my small hotel had one, which she used to make a latte with rather than drink the rather tepid offering at the more tea-oriented hotel. That's when I decided to get one. I'll be taking it on future trips. Some come with travel containers; this one didn't. The only learning curve was making sure the cup or pitcher for the cream is deap enough not to splash out the cream. I think I'm actually using a little less cream than I used to because the volume increases so much. I use cold cream, not heated (I used to heat it in the microwave when I was using the NesPresso.) I find I like the initial contrast with the cold cream at the top, then I stir it down into the coffee. The Starbucks coffee is excellent. I've used it for iced lattes in the past, so I knew it was good. I can hardly wait for a heat wave to make them with this frother. I did try to beater attachment in eggs when I was making an omelet. Not worth the trouble -- first, the bowl I was using to beat the eggs was too shallow and egg got all over. Second, a fork works just as well. If I were whipping cream, I would definitely use it.

Works great and so much fun!
Color: Black
How did I live without this for so long? I love this little gadget! It gets used multiple times a day. It's not only great for frothing milk but it will whip eggs for a recipe and stir other ingredients as well. People who have complained that the stirring attachment was missing a piece did not read the description. The picture clearly shows there is no "boot" on that attachment, you don't want that one to spin like the frother. The Frother holds a charge for quite a while as well. I use mine multiple times a day and it is still holding a charge after weeks of daily use. Great item!

Disappointed
Color: White, Color: White
Powerful, but the description differs from the actual specifications, and the speed cannot be adjusted.
