Question: Does Amazon.com ship only the new/improved version of the j/fit Medine Balls Max?
Document: HOMERUN!j/fit hit a home run with their latest version of the Med Ball Max. I have been using their original version and haven't had any problems with mine, but the new version is so close to the Dynamax ball, I am having a hard time telling the difference, except in the price which is about half.If you want a great ball, durable, with a feel and touch of a Dynamax at half the price, I would highly recommend this ball. Thanks j/fit for giving us the quality we are looking for at a great price.
I run a small X-Fit operation in Ohio. I bought this ball to save some money. About a month after purchasing the ball, the seam started to open up. This ball may be OK for personal use, just not commercial. I called Amazon about the problem and they sent me a new one. So far the new one is holding up great.
The j/fit med ball is great quality for the price! Not a Dynamax but for the price it is definitely worth it!
Great material for a ball, cheaper than the competitors! Have used both this one and the other j/fit  med ball and love them both. Would definitely order from this company again!
j/ fit 12 lb Wall Ball&#34; Increases your speed, strength, coordination, & conditioning.A great tool for Crossfit.. fast shipping. great price..nice product for less price
I've had my ball about a month now and with slight use it is holding up well. My clients love it because it is soft anddoesn't hurt to catch. I have the 10lb version and I am a big fan of these balls. A must add especially if you can't affordthe &#34;bigname&#34; brand.
I got this for my wife and we've had no issue at all. It seems that this ball will last a long time. We only use it for wall ball toss. I don't think it's a good idea to be used for slamming it. I liked the product that I not only purchased a slam ball by j/fit, I also purchased a 25lb wall ball as well. Will right review for those items later. Highly recommend.
I've had the 10, 15, 20, and 30 pound Balls for about a month now, and I can't say enough about them. I've been doing crossfit for a couple of years and have used dynamax balls until this point. The new material of the jfit balls is perfect and is identical the the dynamax, also the balance of the weight and the ability for these balls to stay perfectly round is very impressive...keep in mind I let these balls hit the ground from a height of 10feet when I do wall balls.
When I first ordered the jfit balls the 15 & 30 pound balls came in the old material that has been getting the bulk of the negative reviews, when I called jfit customer service they had me email a picture of those 2 balls and told me that they were the old material, with that said they had an email confirmation to me within 5mins that the 2 new balls were already processed to be shipped free of charge and would be at my door in a weeks time.I am looking forward to get these to my door in the next couple days, and I'm getting ready to order 3 of their slam balls next.If you are in the market for a medicine ball to use for wall balls/shots...don't waste your money on dynamax, these are every bit as good AND EVEN BETTER then dynamax, and the customer service makes the choice a no brainier.
The ball is good for everything so far except doing a slam ball workout with it. The first day I used it one of the seems starting ripping when I was doing slam balls. I've seen people do slam balls with the dynamix wall balls but I guess there might be a reason J-fit balls are less expensive
Answer: yes
