Hiya,

Sorry bout late reply. That one is basically the same thing as the dearer WOW! screen protectors. It probably doesn't have all that marketing JAZZ like Anti-glare / PET coating etc.

You'll save cash buying the zero air and tbh the 3ds xl screens were re-engineered to be naturally anti-glare anyways. From 12% on the original 3ds to around 2-3% on the xl.

It'll do the same job so don't worry about all the different versions. Just make sure to follow these steps for top & bottom screens:

1. Align screen protector. Triple check it is perfectly placed. Then use cellotape to temporarily secure it to your 3ds on one side of touch screen depending on handness ( leftie or rightie)

2. Give contact side of screen protector & screen a good wipe with supplied cloth (although an anti static glasses cloth would be preferable here) you can also wrap a piece of cellotape around your index finger to gently dab at the screen to pick up stray dust particles.

3. Triple check everything is perfecftly placed and dust/hair free before you peel the no 1 tab to secure it to your 3ds screen. Mistakes are hard to rectify once you lay the protector down fully. Once done peel off no 2 tab to finish it up.

I find it best to do it in the bathroom as its the least dustiest room in the house plus if you have a shower first to steam up the room. The steam collects up the excess dust and the bathroom fan then extracts it all leaving a close as can be dust-free room.
