Strengths: These are my favourite energy bar, partly because I like the flavours - especially the fruity ones, but mainly because they're so chewy and take a bit of eating, unlike other flapjack bars which are gone in 2 bites. That said I don't use them whilst training, but as a pre run boost
Weaknesses: As someone else commented they do stick to stuff, lost count of the number of newspaper pages I've stuck together.
'REALLY WANTED IT TO WORK - BUT SADLY IT DIDN'T FOR ME'
Strengths: Uploading of runs onto PC. Looks good
Weaknesses: It measured the same 4ish mile run at anything from 3.5 to 4.5 - not really good enough. The avg speed per mile is rubbish as is the run mapping software on the website.
Overall: Initially I thought that it was really neat and was happy it was giving me a good idea of how far I'd gone. However, over the weeks I noticed that it was giving wildly different readings for the same run - which made me question every other distance it had previously measured. Whilst I didn't expect it to be bang on accurate, I would at least expect it to measure the same run at the same distance each time. The "avg" mile pace is nothing of the sort, but rather the pace that you were running at the point you complete each mile. What is the point of that feature ? Finally, when trying to map my runs on the website, it seemd to give up after about 5 miles, but even on shorter runs it couldn't cope with going over the same bit of road twice - so no good for an out and back route. Although I initially thought it was a very reasonable price - if it doesn't work then it's not good value.
Weaknesses: Although SIS make a thing of their bottles being easy to use, with portion markings on them for removing the need for a scoop -you try lifting (and pouring without spilling) a 1.6kg bottle of powder into a flimsy sports bottle. I use a funnel, but still manage to spill some especially when the container is new and nearly full.
Overall: Really seems to work, can do a tough session Wednesday eve and still feel strong enough to tackle circuits on Thursday. Might be physcological, but if I don't have any my work out the following day seems to suffer.
