On one hand these blocks are nothing special, however they get the job done very well. They are a good size, interlock well, and I've found a variety of uses for them in the gym. I've used them for block pulls, deficit deadlifts, to raise my dumbells a bit to facilitate chest supported rows on my bench, as a step-up platform, and as a small step platform to facilitate weighted dips and pull-ups. They are quite versatile, but also relatively expensive. I'm sure someone with time, ingenuity, and some skills and rig up something as effective, but for the ease of use and convenience I really like these blocks. If you plan to use them for block pulls or as a step up platform, you'll like need at least 5 pairs of blocks (10 total).
