Whats the BEST Pedometer? Should I Count my Steps??

My first one many years ago was a rosemary conley (sp). That was great, When I started walking again I went through several cheap ones, found they stopped working after few days, if they ever worked at all, or were terribly inaccurate. Would count six steps at once, if I sat down, but half the walking steps wouldn't register unless I stamped my feet down.
Latest one was a Tanita, That was brilliant until I accidentally put it through the wash. However at just under the £20 mark rather than replace it decided to put money towards Vivofit instead.

Although your normal step,s eg around the house, at work etc are included in your activity level. Counting steps can help, if your getting too few steps a day can always have walk round the block, to up them a bit (I work a split shift on Fridays and my step count is always lower that day).
I don't generally log walking round the village , however if I go for a long walk, (usually over an hour) Yes I do log that as it isn't a daily thing.

I would say Fitbit Zip is the best in my experience for the purpose of counting steps. It's small, discreet, you don't need to bother with charging it every few days, it's not affected by arm movements so the step count is more accurate, Fitbit as a brand is popular so it syncs well with many different services including MFP, and this particular tracker is on the cheaper side to boot. It may not scratch the gadget itch if you like shiny gadgets and techy knick-knacks, but it does exactly what it needs to do and does it well.

The purpose of counting steps is to track your activity level. Activity level shouldn't be counted towards exercise if your activity is fairly consistent and you are using a TDEE calculator to estimate your calorie burn. MFP offers the option to add any extra activity as exercise if you are set to sedentary. This could be helpful if your activity level is not consistent, and it could also be helpful if you want to find out what your actual daily activity looks like (for example, my current step count is considered "lightly active" and used to be "active" a few months ago).

It is worth looking around for the right one. Next year I may upgrade to a better Garmin or Polar due to the swim options. However its just something im looking at.
My Ffirst activity tracker after a range of pedometers was a misfit, which unfortunately conked out after first night. (hated the tracker but did like the ap for it). My lodger has later version of the vivofit, yet its wasted. He loved it the first couple of weeks but hardly glances at it now. He may as well have bought a pedometer at couple of quid.
