This is a very cute and sleek frameless candle. Colors are very bright, they are light, take three AA. It is a twist off from the bottom to put the batteries in.
You can download the app and choose from different settings like solid colors, pulsing, flashing using Bluetooth. The app for me only asked to use the Bluetooth capability and did not ask for permission to access the rest of my phone.
If you don't want to use the app then turning it on will default to the slow movement through the colors. Which in my opinion is quite relaxing.
This would make a great gift, and add a bit of umph to a room when lit or can be relaxing.

Very cool product and easy to adjust settings via Bluetooth on my phone. I bought this set of 3 bulbs as individual gifts (including one for myself). I may buy more.

It's not super-bright, but is more of a soothing light, and it's relaxing to just sit and watch it change colors.

Great product! Love the possibilities with this lamp. The app works great, lot of different modes, you can pick every imaginable color, and it's the coolest when you have three or more of these.

The only downside is the 3 AA batteries it requires.

I bought this as a night light, but it doesn't really shine as brightly as I had hoped. It does have the Bluetooth and app control feature, which is finally in English (it was previously all in Chinese!), but it definitely is more "decorative" than it is useful for a nightstand. I had hoped for more largely b/c the price point was so attractive compared to other options, but now I see why.

This is one of those products that is fun, but definitely is what one would expect from such a bargain price point. I would not recommend it unless you wish to use it as mood lighting or ambient lighting...or perhaps buy a few for a party setting, since you are able to change it into a range of different colors. However, it is not something I would recommend as a night stand lighting option, based on my use.

The on/off switch is also oddly placed INSIDE the device, making it a tad difficult to even turn on if you have larger fingers (FYI!) The incense pads that supposedly provide you an aromatic option fell abysmally flat, with no real scent in the room. Apparently, the heat from the device is supposed to warm the provided aromatic pads ---which also are a challenge to insert due to the small size of the unit--- but there was no appreciable difference in the smell from the light, once activated for a 2 hours or more. All in all, an inexpensive trinket, but definitely not a lighting solution for all.
