Regretting Garmin 955 purchase

Hi all, I lost my forerunner 55 and was deciding between 255 and 955, I ended up deciding on the 955. But after about a day of use so far I am disliking it, it feels way too bulky to me, ridiculously thick, I know it is a stupid reason but I am used to the small profile of the garmin 55. I can't return it because the store says I have turned it on and that has activated its warranty to Garmin. Does anyone else regret the 955 purchase?
