Pros: Once I got the product working, it is smooth sailing. Happy to IR sync my Pocket PC, then use WiFi. Also to sync my IR Nokia 6340i.

Cons: Just installing the software from the OEM CD wasn't enough to help ActiveSync see it as a "virtual com" port. Go to Manufacturer's site http://www.syba.com/product/42/01/05/index.html for the product. Click the download tab and download "Moschip MCS7780 driver set v1.0.0.10 for Windows 98 / 98SE / Me / 2000/XP" for model "SD-IRU1F-M1". Next, extract the files in the zip and open folder "MCS7780_Ver 1.0.0.10 Driver" and run "IRSetup.exe". After the install, attach your new USB-IRDA bridge adapter and follow directions. This allowed Active Sync to see IR as a virtual com

Pros: Comes with nice little 2ft extention cable. The adapter would be great if I could even install it...

Cons: XP just says that the USB device malfuntioned... thats all I can get. I can't get it to install as anything other that "unknown device" and Device Manager doesnt like the driver on the CD. The CD doesnt have a setup program.

Pros: I wanted this to use with my Polar S625X Monitor. Polar's IrDA adapter costs 5 times as much. The driver disk that came with this was blank, so I had to go to the website. There was a Moschip MCS7780 driver set and a Tanic S110 driver. The Moschip drivers were not recognized under Vista, so I tried the Tanic. Running the Setup.exe under the WinXP_2K directory installed a driver that works fine.

Cons: No claimed Vista support, although it works once you find the right driver. The "blank" driver CD included was a first for me. The www.syba.com site is a little difficult to find the downloads for the right product. Hint is to look under "Networking" and "USB Wireless Network Adapter"

Pros: None - does not work.

Cons: Driver won't install. Driver downloaded from web site won't install either.

Overall Review: Waste of money.

Pros: Worked perfectly out of the box - I literally "plugged and played"! I ignored the driver CD and plugged the device into a USB port; XP Home SP2 loaded drivers, installed a new control panel, and voila - data transfer!! Very reasonably priced; also compact - smaller than most flash drives.

Cons: Sure it's slow, but come on - it's IrDA!

Overall Review: Support personnel should DEFINITELY carry one of these around for on-sites - this device worked a miracle for me getting data off an old notebook with no CD, floppy, network card, or working modem - but it did have IrDA!

Pros: Nice and small, comes with a little USB extension cable and mini driver CD. Works great in Win XP.

Cons: No support for XP Pro 64 bit, so I can't use it on the machine I intended :(

Overall Review: It'd be nice if NewEgg sold an x64 compatable adapter.

Pros: cheap

Cons: doesn't work. no manufacture website, hence no driver update. It DID detect my cell phone and install the driver for the cell phone but can't transfer data...

Overall Review: not worth to RMA it. The shipping more then the price of refund after restocking fee. I have another module that works but left at home. Now this one doesn't work. And I will ask my family to mail the old one to me. Waste time and money.

Pros: Nice device, no problems with multiple installs to multiple WinXP SP2 machines. Since I usually don't keep track of my install disks as well as I should, I tried once to find the right driver on SYBA's website but had no luck. I finally found original install disk, so the drivers for WinXP/ME/2K/98 are now here: I saw the other reviews about people having problems finding the right drivers, so I put them online in case anyone (including me) can use them in the future.

Cons: There is a tiny green light that intermittently blinks all the time once installed, but a perpetual blinking light is pretty standard for most any dongle, and at least the one on this device doesn't distract me nearly as much as some bluetooth dongles I have tried. (and can be easily covered over with electrical tape)

Overall Review: I have been using this with my Polar s625x watch nearly ever day for the last year or so, and it has never failed. The real bonus is, besides being a lot smaller -- it's also much cheaper than Polar's proprietary IR device.
