So, going back to that quote from the LG's website, is this a 'slim and stylish' flip phone? Well, I'm not sold on the stylish angle, to be honest, and nor is it overly slim. And as for the 'changeable font sizes', well, yes indeed. In the settings area there are no less than five sizes to choose from: normal, medium, large, very large, and super. Between the five sizes there is quite a range, and if you find some handset fonts squint-inducing, the larger ones here should suit you well. Though of course, the larger you make your text the less of it you can actually see on screen at any one time.
This is all good news if you sometimes struggle with smaller mobile phones. But if you are looking for a top-notch feature set to go with the usability plusses you could be looking in the wrong place. The KF300 is a quad-band handset but it lacks fast data capability. There's no Wi-Fi or GPS, and there's no accelerometer.
There is a mere 14MB of built-in memory, too, but you can build on that with microSD cards, though the slot is very inconveniently located under the battery requiring a power down if you want to swap cards.
If you want to use the handset for music playback make sure you put any tunes into a file you create on your microSD card called 'Sounds' or the KF300 won't find them. Really, that is unforgivable. It is old fashioned for a handset not to be able to locate tunes anywhere on a memory card and compile them into a library, but the problem is compounded by the fact that LG has come up with such an ergonomically usable phone on the hardware side of things. Bah!
LG has eschewed the concept of a 3.5mm headset jack on the phone in favour of a proprietary connector that is shared with the mains power adaptor. This is located on the side of the handset, where it is ripe for pocket-snagging. The good news is that just past the microphone there is a 3.5mm jack so you can use LGs own in-ear buds or your own favourite earphones.
