Rated 4.0 out of 5.0 by SGDaVinci RTFM - Design Has Been Changed/Improved
I might be wrong, but it seems to me that SL-6166-C has been changed in-store to SL-7366 (not online yet) but images, descriptions and price match up.
The technology has changed thusly:
Tone selection - Old: Jumper, New: Dip Switches
Push button pairing - Old: Jumpers, New: Within 20 seconds of plugging in chime, press and hold push button until chime sounds - this can be done to pair a number of pushbuttons. There is a procedure to erase all pairing.
Battery - Old: 12v 23A, New: CR2032 button battery (CR2025 also fits and works)
I've compared both in real world and the new model's range and sound quality/volume are superior. Also pairing is simpler because there is no need to touch jumpers nor dip switches which require removing screw from chime and using needle-nose pliers or tweezers, and opening up push button - dip switches are only for tone selection, not for pairing.
Also, instructions are clear and simple, but you have read them ;-)
There's a review by MilitarySpouse fromAlexandria, VA which incorrectly says there is no way to pair additional buttons. My guess is that either they did not read the manual, or referred to instructions for an older/different model.

Rated 2.0 out of 5.0 by MilitarySpouse Great sound but will not adapt to other wireless doorbells as advertised
The sound of the Westminster chime is terrific but the unit does not function as advertised. We wanted to pair up a different doorbell button onto this unit and the packaging advertises it can be expanded to more buttons. BUT, there are no jumpers inside the main unit so that the frequency can be changed or matched to another button. So crazy! We took it back and got a different unit, the stand alone doorbell to be paired with a wireless button to be purchased separately. Again, no jumpers so there is no way at all to pair this with any button! Back to store we must go again. Guess the only way to make this work is to buy a unit that comes with one or two buttons and forget about pairing anything else with it, unless you can find an older version that is still made with the jumpers. Good luck.

Looks OK, installs easy, affordable. Unless you plan on installing receiver within 12 feet of your door, shop around. I finally extended the range to about 20 feet by opening the receiver and extending antenna wire outside the enclosure. I had some success without this modification but it wasn't reliable,
maybe 25% of the time it worked at the 20 foot location

Rated 4.0 out of 5.0 by RTPKEN Works Fine
Door bell is about 12 feet from the chime unit. Button needs to be pressed firmly to activate, but it works. Was getting some "false" rings, so just revised the ring codes. Not difficult, but the pieces that need to be moved are small; suggest needle nose pliers to help. Chime unit is located in a central entryway and is loud enough to be heard in upstairs and downstairs. So, other than a few false rings (which hopefully the changing of the code will fix), we are very happy with the unit.

Rated 5.0 out of 5.0 by Georgia Hey, it WORKS!
Bought a doorbell extension. Didn't work. Sent it back and bought this one. It replaces (or augments-depending on the person ringing) the original and can be plugged in wherever you want it to ring. The only problem now is getting people to push this button, instead of the one on the wall (which has tape over it with an arrow pointing to the new button). Sigh. Still.

Rated 4.0 out of 5.0 by OfficeManager This product serves its purpose
The product is good but the volume is loud. There is an adjuster but even the lowest volume is still too loud. The only improvement I would have is to have the manufacturer adjust this. Otherwise, the product is good and it serves its purpose.
