Excerpt: I've owned the initial 2 phone system for over 5 years and recently added a 3rd handset for the garage. The phone is of solid construction. Battery life is amazing. It is not uncommon for the phone to last over a week on standby. The handset is comfortable to talk on for extended periods of time.
Summary: I ordered the Panasonic KX-TGA401B Extra Handset for KX-TG4000 Series Cordless Phone to replace one we lost. We use this as our home business phone and it is very sturdy. The replacement was perfect and I can highly recommend this product.
Summary: I can't fairly rate this handset because it was not compatible with my old (really old) system. However I returned it with no trouble Then bought a new Panasonic KX_TAG470 It is a cool phone system. Check it out and buy it. Don't make the mistake I did!
