This is smaller than I'd assumed, but I'm glad about that. The variety of white noise and fans sounds is great. There's a pink/brown noise (deeper, lower frequency) that we love. I bought 2 on sale for $19. Louder and better quality than thought it would be at this size and price.

This model is the best yet. It synced immediately with my phone, which is the only problem I've always had with the Flip models. I like that JBL decided to get rid of the charge port cover. This speaker is loud and the bass is on point. I've bought just about every decent brand out there, but I'll only by JBL from here on out.

I was very pleased with this product. It’s a small and compact device that delivers a powerful and bright display. I was able to watch a movie with a crowd of ten people. Everyone was able to see it clearly.It even works over Wi-Fi which means you don’t need any annoying adapters.Great product!!

This little box packs great sound. It was better than I expected. One of my best purchases!

I’m an electronics geek who uses dusters often. Computer case and filter maintenance is a monthly thing. I was excited to receive this. I was not disappointed in how it performed at all.Performance after a full charge:* My run time was just about 16 minutes and 16 seconds on high before the duster shut down and indicated it needing recharging. Sitting this upright (on high), it will just blow itself over, or try to spin on its side on a smooth surface. I laid it on its side on my bed when testing duration time. Window curtains and cords from blinds 8 feet away from the nozzle moved around quite a bit.** The force it puts out, especially when coupled with the soft brush attachment, should handle all the dust bunnies and debris your electronics will ever see. The amount of dust and food fragments it ejected from my computer keyboard was quite impressive.*** From a dead battery, it took 3 hours and 30 minutes to fully recharge.The red LED charging light above the power dial flashes until charging is complete, then will stay on. In use, this light stays on, but will flash when the battery needs recharging. To turn the duster on or off, push in on the dial; rotate dial to change blower speed. I didn’t find the speed adjustment useful as I just used it on high all the time.It handled my monthly electronics dusting routine, plus blowing out dust and crud from under my car seats, clothes dryer and refrigerator where a vacuum won’t reach. With 16 minutes of runtime, I ran out of things to dust around the house before the battery went dead. This duster clearly outperformed any compressed gas air can I had ever used and is definitely powerful enough for my needs.I think this is a much better value than buying compressed air cans and will be handy to have around the house in general. I keep it in one of our kitchen drawers as it doesn’t take up much space.

Crisp, clean sound. Powerful output and easy connection! I love my new M90 speaker!

In general, I really like this compact Bluetooth speaker. It has excellent volume and is able to fill a 15 by 16 bedroom easily, even at just 20 percent volume. The EQ is pretty flat, but still provides a full sound. I was able to get good bass down to about 90Hz without losing clarity in the vocals and highs.One of the standout features for me is that it can play off an SD or TF card, although it doesn't have the ability to randomize files. This isn't a big issue though, as there are plenty of free software options available online to fix this.One downside is the LED lights, which can be quite bright and there's no way to turn them off. I was able to cover the light source with a piece of adhesive rubber without impacting the performance of the speaker. The included wrist strap is a nice touch, but it can be a bit difficult to thread through.The controls can also be a bit frustrating at times. The volume is controlled by a long press, but short pressing skips songs. This can lead to accidentally skipping songs when trying to adjust the volume.Overall, I would definitely recommend this speaker for anyone looking for a good Bluetooth option for music or even for connecting to a TV. It's great to have the option to keep it plugged in or use the long-lasting battery. And the added bonus of being able to use it as a portable phone charger is a nice touch.

I have been using another brand in the past that I was fairly happy with but the power in this one is unbelievable even if I have to brake fast my phone never falls off would definitely purchase again!!
