I've used this cork block for about a year and am ordering another to have on hand. This listing is the same as when it was just a cork block with "GAIAM" on the side, but the pictures are different. Judging by the reviews, it looks like you have the chance of receiving the original stock, or the newer design. So you may want to keep that in mind if the looks are important! Very Sturdy. I've used foam before, and a cork + foam together in some cases (desperate times, ok?), and my practice would always suffer when using foam. There would be no stability, I struggled with grip, and in some cases, the foam block would collapse. Never experienced those issues with a cork block, and it doesn't become a distraction. However! It is good to note is that for head or back support, the firmness of the cork block may be quite uncomfortable. You may find foam is better here. Another pro is that it doesn't fall apart like foam and plastic ones do. So far my old one feels like new and is still in one piece. Only differences are that it doesn't have that "fresh cork scent" anymore and it now has a few light oil stains. Which, if you are an oily person or like to use oils regularly, would be something to note. Your oils won't affect grip, but the cork absorbs them and you'll get a spot where you regularly place your forehead, for example. Personally, I am more disturbed by the oil residue on a plastic block, or worse, you go slipping because your moisture has nowhere to go. On plastic, though, you can just wipe it off. On cork, the oil is there to stay. The stains are dark at first, then fade over time. So you will end up with an interesting looking cork block over the years. . . but you can rest assured that it is anti-bacterial. :') The weight is perfect! If I do core exercises, I'll actually feel like I'm doing something. For reference, my go-to barbells are 20-35lbs. If you are just starting a healthier lifestyle, or are ill, these may be considered heavy, in which case, you may want to start with foam and then work your way up to using cork. The price may also be heavy, but one thing I am finding with cork products is: I have to replace them far less often (haven't needed to yet!!). This creates less waste and more funds in my wallet over time. They also need less maintenance. so you need to use less time and product to clean them. Hope this helps!!
