I just buy the Shake Weight at Wal-Mart for -lrb- ... -rrb- in they as see on tv section to try it out . so far 9 out of 10 as see on tv item that I have buy have a be a joke . -lrb- Shoes under be the only one I keep and even then I almost do not because it be so flimsy . -rrb- I like to try out the product to see if it work and because it be Wal-Mart I have no problem return it . I do not know how I be go to do that with the Shake Weight because as far as I can see there be no way to test to see if it actually work . how long do it take to make my arm look better ? -lrb- I think this be why there be virtually no review as yet , people can not tell if it be work and they get tire of it before it be obvious that it be or be not work . -rrb- but here 's what I have get so far : `` Feel the burn '' : it be true that you biceps do start to `` burn '' while you be use this product but I think that be from have they unnaturally clench for 6 minute straight while you shake yourself to death . -lrb- yes , this be how the product work , you bicep muscle clench up and stay that way while you be do this exercise . -rrb- I be always teach to do `` rep '' during strength training which allow the muscle to tense and rest every few seconds while you work it use resistance -lrb- i.e weight -rrb- . `` it be a weight '' : no , not really . it have a little bit of weight to it but there do not seem to be any resistance to this tool and it seem that 6 minute of continuously have you tensed muscle shake would just hurt you -lrb- hence the `` burn . '' -rrb- not to mention that even if the product do work there be no way to add more weight to it and you muscle would quickly outgrow it . then it be obsolete . `` shake '' : when do shake fat to shrink it come back in style ? remember those old contraption fat man in sweat shirt would be strap into and it would shake they belly in the hope that it would make they smaller ? there be a reason you do not see those anymore . they do not work and they be dangerous . `` Dynamic Inertia '' : go ahead , Google it . you will not find it anywhere on the web unless it be in connection to the shake weight . when do a product get to coin new physics terminology ? and exactly what do it mean ? `` it look silly and kinda pervert '' : the product do not claim this but almost everyone else do . the product do look like a elegant massage toy and face it , you do look and feel silly shake you arm fat everywhere . -lrb- hey , if you do not have arm fat then you would not be use it . -rrb- and pervert , well , there be even a spoof video on YouTube that be so r-rated that I refuse to discuss it further here . other review on the web : there be like 4 and I think they be all write by the people who make -lrb- or sell -rrb- the product . they have almost nothing negative to say about the Shake weight and one woman even claim it make she boob bigger . yeah right . and finally , the price : -lrb- this be maybe the only good thing about this item . -rrb- it seem as if the manufacturer can not agree on how much this thing should cost . they infomercial list it at a bargain at 19.99 plus shipping and handling -lrb- which I think be like another 7 or 8 buck -rrb- and Wal-Mart have it simply for the -lrb- ... -rrb- . so what be up with they sell it on Amazon for almost double the price ? well , it turn out that the the manufacturer be not the one sell the item . jwwbooks4 be the company sell it through Amazon and I guess they be hope to make a big profit . it be a little shady in my opinion . final Verdict : I guess I be go to see if actually work . hey , I have get 90 day through Wal-Mart , but I be not go to hold my breath for result . if you do decide to try it , go to Wal-Mart and save yourself the shipping and the handle through the infomercial , or the extra 17 dollar they be charge through Amazon . hey , you do have the option to save yourself the headache altogether and do not bother to buy it at all . you can get a decent set of weight for about the same price .
