If your gut is about the same shape as mine( not as flat as it has been!) the fluke rests nicely and the gel filled neck pad is comfortable all day long. Not the most important things I know but how many testers are you going to buy in the next 5 years, how often are you going to use it and how long are you going to use it per day. Nothing irks more than a bit of kit that costs a lot of money but is uncomfortable to use. I also heard a rumour that uk spec flukes can be ordered online from the states cheaper than here. Don't know how much truth in that.
