im just gonna put in that i own poweriZers and ive had them sence january and started useing them in Febuary and used them every week, twice or more for at least 2 hours at a time and the only problem is that the white T thing has fallen out and ive inspected every inch of the springs and there are no scraches or anything (apart form the ones i know i made myself) and they perform alright.

In NOT saying they are the best brand or better than poweriser, its just what i have used, ive never tried any other brand so i have nothing to compare it to, im just saying that that arent complete cr**, they are fine.

P.S: Dont kill me or flame me or anything....

i tend to build up speed then moon walk, do a huge kangaroo leap and then jump as high as possable and some times i get up to what feels like 5 feet, i looks like where my head usually is so i just guesstamate at my hight, its fun all the same

i like to bock on only concrete because on grass i tend to slip and fall and the sam for bricks, never tried sand before tho.... 

yeah i realized that mistake a little bit ago, sorry about that, i had my mind on other things.

Hello everyone!

The name everyone calls me is Zan, i am a 14 yr old boy who loves to block.
I have a pair of the PoweriZser M60's, yeah I got the adult pair becuse the kids pair i know i would have no fun on.
I can jump to about 4 or 5 feet, i never have tried big tricks like grabbing the springs or flipping (everytime i try i end up on my butt)
I live in Boston Massachusetts, USA, I'd love to meet up with someone who blocks in the boston commons or something, but i think im the only one around here with them
so yeah that me
-Zan

the same thing kinda happened to me, i was going to jump up some stairs and i think i landed it wrong and i tried to catch myself but in the prosess i did something to my knee and it hurts all the time, hope its not too bad and ill just heal in a few days and back into action.

that must really suck, i have fiberglass i beleve and mine havnt had and huge problems to speak of. I feel your pain nonetheless.
