Review (4/5): Much better than the flimsy plastic guides included with the Magic Clip
The original snap-on plastic guides that come with the Wahl Magic Clip bend easily and always feel like they're going to pop off.
This guide is much more sturdy - it's made of stronger, stiffer plastic and is reinforced with a metal clip. I'm no longer afraid that I'm going to give myself an unintentional buzzcut down to the skin.
Another side effect of the sturdier attachment of this clip is that the clippers are much quieter - with the original clip attached there was a lot of rattling because it was loose.
