Well built and they work brilliantly. Many others have said that the plastic ones are no good but I think these are excellent quality. You wouldn't want them any heavier, which metal construction may give. They have a large handle to spread the weight, are really solid and don't slip because of the non slip rubber on the base and I couldn't want for more. Thank you Tony Horton!! I'm in my final week of P90X and have already bought P90X2 - Bring It!!
Took a few mins to work out how to put it together but then its brilliant. Fits in our doorway when I didn't think it would. The foam is just enough padding to protect yours hands without being bulky and the different hand positions are excellent to work every angle possible. You pay for what you get and this is quality - thank you P90X, Beachbody and Amazon.
