This special edition Philishave Coolskin is a 'super-sized' limited availability version of the HQ6740 to celebrate 400 million Philishave shavers sold. It has since seen full time acceptance into the range under the guise of HQ6764, featuring revised body graphics<br><br>It features the usual Coolskin cutting heads and internals but with the added bonus of a 1 hour charge time as opposed to the HQ6740 time of 8 hours. The general appearance of the shaver has also been given some jazz and features a new fresh, more polished look. The replacement coolskin cartridges are the usual cream or cool-gel replacements and offer the expected excellent soothing capability.<br><br>Don't be put off by it being a limited edition. In terms of spare parts, replacement cutting heads and all internal spares it has the same excellent availability as all other Philishave shavers.<br><br>For the small premium over the HQ6740 I would definately opt for the this model if only for the 1 hour as opposed to 8 hour charge time.
