5 out of 5 eggsGood Product

Pros: Brought for home usage and it works great ! I havent tested the bluetooth feature completely, but the voice quaility and signal strength is very good. Very light weight comparing to other phones like uniden. I would refer to my friend.

Cons: It should have 110- 240volts charging adapter :(..

5 out of 5 eggsKX-TH1212B is solid

Pros: Links up readily via Bluetooth to my Samsung U960 Rogue, which lets me place my phone where the cellular reception is good and keep a handset where the cellular signal is unacceptable. Solves a difficult problem. I've owned Panasonic landlines for >10 years and they have always been reliable performers with a great signal. The same can be said of the KX-TH1212B. And at the Newegg price it's a steal.

Cons: There is a slight delay between answering the phone and when the other party can start hearing you ("Hello, hello?"). Annoying at first but manageable after you get used to delaying your greeting for a beat. The advantages far outweigh this shortcoming.

Other Thoughts: The KX-TH1212B doesn't have an answering machine built in, but that's good for me as I already have an answering machine, or I can rely on my cellular voicemail. Also, the KX-TH1212B cannot access any of your cell phone features, other than making and receiving calls of course. There is no access to your phone's contacts list. Again, not a big deal to me.

2 out of 5 eggsWorks...then stops working.

Pros: Handsets and recharger bases can be used with other Panasonic systems.

Cons: Linking your land-line handset to your mobile phones with Bluetooth is a wonderful idea, and a few manufacturers have tried to implement it, but I haven't found a single one that will stay working for longer than the warranty. I couldn't get this system to work reliably.

Other Thoughts: I still use the handsets for this system to expand a compatible Panasonic expandable system. There are only cosmetic differences with this particular handset generation across products.

5 out of 5 eggsWorks for me w/multiple cellphones

Pros: I got the Panasonic Cell-link because we have really terrible cell coverage in our house, to the point that we could barely use any cellphones.

So far, it's been great.

I've partnered this unit successfully with both my Sanyo M1 (Sprint PCS), and my daughter's Blackberry Tour (Verizon).

We keep the M1 on a charger next to the door to our garage, and the Cell-link box is in the kitchen (~20') and it's been fine, both for calling out and receiving calls.

My daughter usually takes her Bberry upstairs, and the link to the Cell-link box is still good.

Voice quality seems good with both the M1 and the Bberry, and we haven't encountered any problems so far with dropped calls.

Hopefully things will stay that way :)!!

Cons: None, really.

Other Thoughts: - We don't use the landline feature.
- It would've been nice if it was possible to import the phone books from the M1 and Bberry to the Cell-link...
- Incoming caller ID generally shows only the caller #, not name, but if you the incoming # is in the Cell-link phone book, it shows the name.
- Interesting "glitch": If you call a cell from another cell, where both are partnered to the Cell-link, the Cell-link doesn't see the incoming call.

1 out of 5 eggsDo Not Buy This Junk

Pros: Allows Two Cell Phones To Link To Base

Base Separate From Handsets

Would Be Awesome if it worked

Cons: Constantly Drops Calls Whether Your On Your Bluetooh Link or Landline

Other Thoughts: Would be great if it worked spent 150 bucks on this when it first came out and got so frustrated I just put it up and away only reason I'm writing this review is I was going to throw it up on eI3ay but saw it's only going for 1 or 2 dollars

4 out of 5 eggsNice

Pros: Great way to use cellular in buildings with low/spotty signal. Connect up to 2 cell phones. AAA rechargeable batteries are easily replaceable.

Cons: There are a few "tricks" you need to learn for best operation.

Other Thoughts: I use with 2 iPhones. I had connection issues at first but after a few calls to tech support I learned the proper settings for the phone. (not sure why they are not factory settings) Now I just have to remember to powercycle the phones every few days (recommended by Apple) and all is well.

4 out of 5 eggsGot it Despite Reviews...WORKS!

Pros: Works as advertised.

Voice caller id is fun and even useful at lazy times when deciding to answer.

Handsets are good size for holding which seems to be tough to find as cordless phones keep getting smaller.

Handsets even have speaker phones which seem to work pretty well based on a couple calls so far.

Uses AAA rechargeable batts instead of some proprietary battery pack.

Cons: Cheap looking buttons.

When making a call through the handset via my cell, seems that I can not do key prompts (ie: press 1 to skip someones voice message, etc.).

Other Thoughts: Seemed like a 50/50 shot that it would actually work based on reviews here and elsewhere. I had to try it as my cell cuts out in my home office (great reception most everywhere else) and my cell is my Work phone! I have a BB Pearl via Verizon. I have taken several calls via my cell and landline and not one dropped call like I have read about. Made calls via cell through the cordless handset and no problems there either.

I will upate this if things change.

5 out of 5 eggsWorks great

Pros: Connects automatically, allows two different cell phones at a time, good range, speaking caller id, input phone book into one handset and it automatically saves to all handsets.

Cons: None so far

Other Thoughts: I almost didn't buy this phone system due to all the negative reviews on here and elsewhere. I really needed something to extend my and my wife's cell phones into the basement since they are our only phones (no land line, nor one wanted). Bought this and as soon as I get into the garage, the cell phones connect to the base station. You can set different ringers for each of the lines so you can differentiate which cell phone is ringing and the spoken caller id is pretty cool. I have my base station centrally located and have never had a call dropped. Our cell phones are a Samsung Eternity and Motorola Rzr2. I highly recommend these if you need to extend your cell phones throughout your house!

2 out of 5 eggsJunk...

Pros: Great Concept...

Cons: If it worked...

Other Thoughts: Got rid of this awhile ago, but wanted to see if any advances were made. Doesnt look like it. With my BB 8820, it worked "OK" at best. With my iPhone, WORTHLESS !!!! Sold it online. Just not good tech yet guys...
