Works GREAT - Almost...

Pros: Small, inexpensive, Broadcom chipset, ver 4.0

Cons: Old drivers, hidden software on install, difficult to setup in Windows with included software.

This will work great once you go and get the BROADCOM WIDCOMM drivers. Don't even install the the disc that came with this, THROW IT AWAY. Goto
and download the second item WIDCOMM Bluetooth Windows Software. This will handle everything you need and connect easily.

on PC1, was able to install the broadcom update and use the dongle with a MSFT BT keyboard right away. on PC2, I couldn't install the broadcom update (it would stop at verfiy device, and give a certificate error). However it was still able to run, I guess with built-in drivers. we'll see how it performs down the road.

Pros: Works, but only if you get the drivers manually from Broadcom

Cons: Disc included doesn't actually install the drivers or anything else successfully except for spyware/bloatware apps. Spot on for other reviews wish I had read them sooner.

If you need a cheap Bluetooth adapter and can't find one reliably anywhere else, this will work but please don't use the CD included. Monoprice really dropped the ball with this one.

Didn't work for me.

Pros: Monoprice's usual fast shipping.

Very easy return process.

Cons: The software seemed buggy, the windows did not display properly and soon.

The dongle showed up in my drivers window but wouldn't connect to my speakers.

Hi Kate,

Thank you for your review and truly sorry to hear about your experience with PID 9386. What OS are you running? What steps have you taken when setting up your bluetooth device(s)? Have you tried installing the latest drivers for the dongle? If not you can do so at the following link:

Please let me know if anything changes after installation. Hope this helps!

Does Not Work For Me

  • Phil,
  •  Dartmouth, NS 
  • 7/15/2015 7:47:21 AM

Pros: Tiny, low cost, quick delivery

Cons: 1. Does not work with my HP ZBook 15 running Win 7 Enterprise 64 bit
2. Very difficult to push into USB ports - took a lot of wiggling and far too much force.
3. Crapware included on install disk - installs invisibly - that is just about a deal breaker for me, even if I could get the dongle working

Horrible experience with this. It paired easily with any device I tried (Blackberry, Samsung tablet, headphones) but would then not connect with any of them even though they all showed up in "Devices and Printers". I first tried the driver disk that came with it. Then I tried the drivers from this page (Monoprice, if you must ship product with outdated drivers, at least include a note to that effect!) Then I tried the drivers from the Broadcom website. Then I tried the HP drivers. I completely uninstalled each one before trying the next one. Tried different USB ports. Same result every time - pairing no problem, but would not connect. I've wasted far too much time and effort on this and I'm done.

Hi Phil,

Truly sorry to hear about the issues you have encountered with PID 9386. Do the same issues occur when testing on a different computer? Should the issues remain, we do offer a one year warranty on this item. If you would like I can assist you in setting up an RMA for a replacement to see if that will work better for you. Please let me know if you would like to proceed with a replacement and I can get that started for you right away.
