I have owned my BT Snergy 5500 Cordless phones for approximately the last 8 years. In that time, I have never once had to replace the rechargeable batteries in the product, although I think I may have to soon as the phone doesn't hold it's charge for quite as long as it once did.
This phone has a built in answer machine which will hold up to 12 minutes of conversation. You can choose to play back your messages either through the handset or through the base. For your answer machine greeting message, you can either have the BT pre-recorded answer message, or record your own personalised one. You can also send SMS text messages from this phone, although this is something I have not yet tried myself.
The directory can hold upto 250 names and numbers, so even if you're Ms or Mr Popular, there's still plenty of space to hold a fair few! There is also a recall button and the last number called feature so you can scroll through if you've called a number as a one off, or one you don't store in your contacts list to save you looking it up again.
There is hands free mode on these phones, which I find very useful and use alot. When you're busy cooking for example, or bathing the kids etc it's easy to just put the phone on the side and carry on your conversation whilst still going about your daily jobs. There is adjustable volume control, whether you have the phone on hands free mode, or to your ear. The volume ranges between 1, being the lowest and 8 being the highest. There are also a choice of ringtones to pick from.
The standby time for this phone is 100 hours and talk time 10 hours.
The phones blue backlit LCD screen shows the date and time and if you opt for it with your phone service provider, will also display the caller ID. Very helpful when avoiding the Mother in Law!
I paid £35.00 for the pair for mine approximately 8 years ago and they have proved to be a very good buy. I would definitely recommend this product and give it 5 out of 5 stars. You can also purchase this phone as a single, as a pair and as a trio.
