Som imbatível durante todo o dia

Aumentamos o volume do nosso jeito, em qualquer lugar. O novíssimo JBL Boombox 4 é maior, mais arrojado e melhor do que nunca, com o potente som JBL Pro que permanece alto e claro, com graves profundos e estrondosos. O AI Sound Boost analisa nossa música em tempo real e ajusta o som para nos dar mais potência com menos distorção, mesmo quando aumentamos o volume. Ele vem com dois woofers maiores, dois tweeters e três radiadores passivos, para que cada faixa tenha mais força e soe mais limpa. Quando quisermos ajustar a vibração, basta alternar entre as configurações de reforço de graves profundos ou vibrantes para combinar com nosso humor. Demos ao design clássico do Boombox uma nova atualização, ele é maior, mas mais leve, para que possamos levá-lo aonde quer que a festa vá: à praia, ao quarteirão ou ao quintal. É IP68 à prova d'água e poeira, portanto, o clima nunca é um obstáculo. E, com até 34 horas de reprodução (graças ao Playtime Boost), estamos prontos para longas jornadas. Com o JBL Boombox 4, levamos o clima e a energia para onde quer que vamos.

Best price for better tasting coffee
Color: Silver
I am a coffee snob. I only get beans. I have been using a magic bullet blender to grind, which actually does extremely well, but the grind wasn't quite even enough. So I found the cheapest, ok quality grinder I could and bought this one. I absolutely love it. It take a while to grind, and it only does a little at once, but whatever. This thing works great and my grounds are now even. The burrs seem to be of decent quality and the whole device works smoothly.

Reliable favorite kitchen tool
Color: Blue
This wonderful tool may be the most used tool in our kitchen. The hardest thing about it is to remember you can push the button and it runs- you don't have to hold it!. The charge on the rechargable battery last a long time- about 1 recharge per month- and we use it daily. We use the mixer attachment most. It works great for protein powders, collagen, iced tea or lemonade mix. It cleans easily and is waterproof- just make sure the cover is over the charging port. We have used it to froth milk, whip eggs, and as I said we use it daily to mix beverages. I worried about the price, but it is a great value because we bought it in December 2024 and it is more powerful and has already lasted longer than two whimpy ones.

Quality
Color: Black
This is by far the best frother I've used. Battery life is great. Its UX is excellent. Feels nice in the hand and has great power. Also like the on/off button as opposed to haveing to hold a switch down. Looking forward to getting their s3 scale.

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.
