I've been looking at those cleats! Can you share more about how they feel different? Is the float less smooth? Do they clip in less reliably? I would love to save the money, but not sure how much I'd be losing out on.
I installed only one on the left shoe and kept the Wahoo on my right shoe. So I can compare and feel the difference between my left and right foot. I also have another pair of shoes that have Wahoo cleats.
The AliEx cleats clip in fine. I did need to fiddle with the rotation adjustment screws more (which are hex screws instead of phillips, which is better in my opinion), and I feel more "spring back" than I do with the Wahoo cleats. Unclipping to me feels more "mushy?" My right foot and my other shoes feel "crisper" in that they rotate free to the point that the spring engages and then releases. The AliEx one feels like I feel the spring engage and from there to when it releases is more vague. Not sure how else to describe it.
And really while it's noticable to me, it doesn't affect anything at all. I can get in and out just as easily.
