How are you liking your powerblocks? Are they better than your traditional dumbells? 
It took a little getting used to at first because it felt like I was putting my hand into a toaster oven. But, I got used to it. It's nice and easy to change the weights.
They look like I am looking into the future, adjusting is difficult? No way! that sounds painful, more power to you , I dont think I could be so committed.  Are the powerblocks part of the BowFlex system?
No, they are a different company. BowFlex has their own adjustable dumbbells. I passed on their version because they look too bulky. 
Do you feel you have gain more muscle with the powerblocks? I want to try them out but I dont want to deal with the discomfort. what do you recommend I do, wondering if you have a favorite workout routine where the powerblocks makes it easier to accomplish
Nah, not really. I just got them to add more variety to my workouts. For instance, I like to use only dumbbells for a week instead of barbell.
nice, I am guessing you are a fan of the bowflex, I feel that system is innovative as the powerblocks? Ive wanted to invest in both but both are pretty expensive. 
I've never really used it. My home setup is free weights.
Free weights do not take much space at home? I am guessing as well you can decided the intensity of the workout with the free weights system. Do you like this set up more, working out at home more than going to the gym?
