3 out of 5 eggsclarity C4230

Pros: Good phone, highly adjustable.

Cons: Flashing power light on mine won't go out. Even with new batteries in the head set and base. Now the speaker (base) unit refuses to work too. Slowly becoming useless and it's $150.00+ to replace.

5 out of 5 eggsOUTSTANDING!

Pros: Reception (handset to base communication) is good over a 100 or so foot range, through several walls and floors. Base has builtin speakerphone (as does the handset), good quality answering machine (recording quality and playback is good). Base has builtin battery backup (takes a couple of AA batteries - so when the power goes out, you'll get a good half hour or so of call ability) . Adjustable ringer volume and handset volume. Handset has builtin speakerphone as well (on back). Build quality is OUTSTANDING. Clarity is a branch of Plantronics - they've been making high quality products for years. The handset volume is "normal" up to about "16". Then its "loud" to about "26". Upwards from there its "EAR BLISTERING LOUD", which is great!

Cons: Speakerphone is simplex (not duplex) - but that's not the end of the world - most speakerphones are simplex.

Other Thoughts: I didn't buy this phone because I'm hard of hearing. I bought it because I have normal hearing, but every commodity run of the mill phone out there has three problems... 1) its built like garbage, has poor reception, and operates at 5.8 GHz... 2) they're horridly quiet and have no volume control to compensate for "quiet talking people" or people with poor telephones on their end... and 3) they result in me smashing them to pieces in frustration. Clarity has been making good phones that operate at 900 MHz (they have 2.4 and 5.8 GHz models as well) for years. 900 MHz is the safest operational frequency for the human body, and is an uncluttered band. These phones are phenomenal, I can't say enough good things about them.
