Reynolds Attack Wheels

Anyone try these wheels? If so, what did you think of them, particularly their ability to climb and descend. Thanks.

Their ability to ascend wasn’t very good, all they wanted to do was descend, which they did very well until falling over. Then I had to run down the hill and pick them up.After 3 tries I went back inside, it was getting hot outside, and I didn’t put any sunscreen on.
Sorry if this didn’t help much.

My Eastons did the exact same thing.
