I have had a CB for a few years now and up until recently, I loved it. Yes, it's more portable, take up less space on your desk but it doesn't always "stick" onto the surface.
I recently became a Stampin Up demo, and I qualified for a half price item, being greedy I went for a Big Shot, thinking I could use it to promote sales at demos/classes etc. Not long after ordering I regretted it, thinking I should have ordered a large alphabet die set or,,,or....BUT I must have had physic powers as just before my BS arrived, I was merrily cutting away on my CB and CRACK. Something inside has just sheered off.
I tried Googling to see if it was fixable and there are quite a few cases of this happening.
I cannot say I didn't get very good use out of my CB, and I cannot say that my BS is better as I haven't had it long enough but I have heard the BS is mechanically better with stronger components inside.
Sorry, I have probably confused matters even more!
