We got some during the pandemic and they were excellent even for dynamic stuff, overhead swings, etc. as they are secure on the handles. Quite a clever design. The only limit was the weight actually, as mine only go to 25kg, so if you can press or pull more than you'll still need something heavier (but still better to buy a couple of heavier weights than a whole set). I was very sceptical at first, but overall I think they are excellent and if I was training at home I'd still use them.
I should've said, I was talking about Bowflex. I've only tried the Powerblock ones at a fitness show, but don't like the frame design. And a quick search reveals that you can get Bowflex up to 40kg, so that negates my earlier complaint (the choice was very limited in 2020!).
