I was dreading another order after snapping my last one, but popping this on took about ten seconds with no tools and it clicks in like it's factory-installed. The build feels solid enough that I won't need a spare for a long while.

My old guard was cracked and letting hair wrap around the roller, but this one clicks in without any tools and feels sturdier than the original. The vacuum is back to picking up everything in one pass, which is honestly all I needed.

Took me about thirty seconds to snap the new one on, no tools needed, and it fits like the original did. My robovac is back to picking up along the edges without flinging debris everywhere.
