(1 star) Does not work with masOS 10.14

By: Alex28
iMac 2013, mac Mini 2020. System recognizes it, but it cannot connect to any BT devices, simply times out. I use BT Explorer (comes with Xcode) to switch between Mac's built-in BT chip and one. Mac's had no problems connecting to same devices. Was hoping to use it instead of Mac Mini's built-in BT as it is too weak.

(2 stars) Manual Driver install

By: gomi
Windows 10 couldn't find the proper drivers for the adapter and Startech didn't have driver download for product on website. I had to use the CD. The CD installer failed to install the drivers for the adapter and I had to use device manager to point to the CD to install the drivers.

(2 stars) Key get more than 30 feets

By: BenB
I bought this 2 days ago to connect my headphones to my computer and I can't get further than 30 feets. I tought maybe it was my headphones so I tried with my phone and it's the samething. someone wrote that it was unidirectional so I tried to align the "signal" with me. Same results. I used a usb extender... tought maybe it was the issue so I removed it. same thing. I tried to put the dongle higher so it wouldn't cause interference with my computer... same result. For now, I'm a bit disapointed of the product. It says 165 feets... I know it's probably on a straight line with nothing in between... but 30 feets... well not far...

(5 stars) Works perfectly with my Mac Pro Tower (Mid-2012)

By: WBCilliers
I bought the Bose QC35 wireless headphones and could not connect to my older Mac Pro. Turns out the Bose QC35 required Bluetooth 4.x, and the Mac Pro has Bluetooth 2.1. So I bought this adapter and it worked like a charm. I can now connect to my iPhone 6S and switch to the Mac Pro easily.

(5 stars) Excellent Device

By: MG2240
This is a very good product. The driver software is very comprehensive and reliable. A big advantage is that it supports wake up from sleep function for keyboard/mouse devices. This is the first adaptor I have come across which includes this function. So far have not found any disadvantages or problems.

(4 stars) a few surprises

By: allthunbs
we defined a requirement for a small computer and purchased an ASRock BeeBox n3000. this design lacks substantial punch when it comes to distance for the built-in Bluetooth. the beebox is attached to a 42" 1080p TV as the primary display. since this TV could be used with a sickbed, it was determined that a Bluetooth keyboard and mouse were desirable. the distance was beyond the capabilities of the BeeBox. I purchased this dongle specifically to handle the distance problem and it works as intended. there are a few things that have proven desirable, the driver software installs a second bluetooth control panel in the computer. this allows you to use speaker support close to the computer and keyboard and mouse further from the computer. there is also another complication. the dongle is directional. make sure you test the directionality of the dongle before fixing your installation. I can find no documentation that indicates what the radiation pattern is. this is good for personal security but not so good when you want to cover a wide area, i.e. a large back yard with a working gazebo. I hope this helps.

(5 stars) USBBT1EDR4 is a very good product.

By: BigMacPoppa
Mini USB Bluetooth® 4.0 Adapter is a fantastic product! Better working range than other Bluetooth receivers/transmitters. Works great with Sony MDR-10R after checking ALL of the configuration for USBBT1EDR4. You MUST install ONLY the last version of the CSR Harmony software; if you have an older version installed, you MUST uninstall the older version first. The new version unfortunately does not include drivers for all of the older transmitters and you can't have more than one version installed at the same time. I highly recommend this product.
