I have the exact same helmet, but from a different brand. (same as same shell design and everything) My purchase was slightly more expensive, so go ahead and buy this, it is quality helmet. It should not wiggle that much though, you just need to crank that dial at the back, and I agree this helmet design is super comfortable, I love mine. Slightly related, but some other companies also have mips adjacent technologies in them, but they don't call it mips for licencing reasons. Those might be slightly cheaper, but you should not skip on this. worth mentioning that the padding is closed, the foam is not exposed, so it is actually a more comfortable wear than the cheaper options and longer lasting.
