Hi everyone, I've probably spent way too much time enjoying all of the comments here the last few months so thank you all. I've learned a lot. Just got my 75D yesterday!

I had assumed it would be one that I could wrap the cord around and leave there during the day - will this be just fine? Thank you in advance!
