SABRENT USB Bluetooth 4.0 Micro Adapter for PC [v4.0 Class 2 with Low Energy Technology] (BT UB40)

This worked perfectly, plug-and-play, with my Home Assistant Green. I purchased it to make my Home Assistant set-up compatible with some BLE smart locks I installed, so that I can run automations and control this device remotely (if I want to let family in while I'm away, for example), and it worked seamlessly right out of the box.There is a ~10 second delay, which I supposed is to be expected, but it works with the lock from around 30-feet away, with a strong and reliable connection.It's small size, stable connectivity, and instant compatibility with Home Assistant make this a win for me.

I picked this dongle up for a specific use-case, and I'm hoping someone might find this useful. If anyone reading this is planning to get this for their Synology DSM running v7+, it WILL work and be plug-and-play, but will only be visible to VM's, NOT docker containers.As an aside, in between the time that I purchased this and got it running on my NAS, I tested it on my Windows PC and it works great! The adapter picked up every BT device I threw at it, including headphones, game controllers, and a keyboard. 5 stars!I specifically bought this adapter to communicate with BT devices near my Synology NAS that was running a Dockerized version of Home Assistant. The plan was to have HA pick up a Bluetooth enabled hydrometer that I use for homebrewing so I could monitor fermentation from anywhere, as well as communicate with a few BT sensors I have for home automation. After unsuccessfully trying to install 3rd party drivers (now uninstalled) to get DSM7 to recognize USB dongles (because for some reason Synology disabled that functionality a while ago), I upgraded to HAOS that runs in Virtual Machine Manager. After initial setup, VMM picked up this adapter automatically (no additional software installs) and the adapter integrated flawlessly into Home Assistant.This adapter is great overall, and picks up devices that are 30+ft away and through a few walls. 10/10 would recommend!

Terrible so far. I bought it for my headset (beats solo3) and it's impossible to stay connected. It REFUSES to accept the headset as a mic! Only wants to play sound, to work as headphones. I've paired my beats with my phone and tablet, mic works fine, I'm able to chat with friends while listening to music. I wouldn't recommend this adapter if you have Windows 10. I have heard people have better luck with Windows 8 or below.Pros: It was Plug n PlayCons: since I ran into trouble, the basic settings Windows offered to me didn't cut it. I had to seek help from the Sabrent device driver, which only lead to more issues in the end. Never thought I'd encounter the blue screen of death 4 times in a row because of a bluetooth dongle.****Edit****I received a replacement for free and it works great. While I'll bump up my rating to 4 stars, I will warn you to be careful while using it!

I researched for quite a while before I purchased this item. I needed to simplify the cords on my desk as I have more devices than I do USB ports on my computer. This meant I kept having to unplug and replug devices which was very frustrating.I started looking for a four port hub that I could use to keep everything plugged in at once. I decided on this item as it was on sale at the time and seemed to be of decent quality. I was happily surprised when the product came and it was even better than I expected. The ports are not too stiff like other brands where it seems to hold on for dear life, nor are they too loose. It also feels very well built like it will last quite a while.Three things to note though, first the blue light is very annoying. I have started turning it over or placing a piece of dark tape on the light to help hide it. I understand they want to reassure consumers it is plugged in and working, but I work at my desk mostly at night so it was very annoying.Second, this hub is only useful if you do not plan to power things from it. Since it is not connected to a power source it cannot charge or power USB driven devices like a powered hub could. This is fine for my needs as I was mostly just plugging in my keyboard, mouse, printer, and external thumb drive but it is something to keep in mind if you are looking to buy the product.(Be sure to read the note just under the last picture that is a disclaimer about the power and wireless devices just to be certain this will fit your needs.)Third, the description states this, but the cord is kind of short all things considered. This makes it a little annoying as it has to be fairly close. However, you can probably use a usb extension cord to keep it out of sight, though I am not technologically savvy enough to know if that would cut back on the power or not.Overall, this is a great product that should last a long time. The price and quality make it a no-brainer. I just wish they would make a model without the blue light and with a longer cord.
