Yoga blocks for isolation

Just seen these at Target today . 100% cork . Big blocks . Two per component i would think . I know people swear by the Herbies isolation blocks .

It should be relatively easy to determine to what extent they isolate or couple. I suspect more the former but the proof would be in the pudding.
