Watch out. This quote above should not be meant to say a
Walmart $3.00 item is the exact thing as a $17.00 item.
Just think of Home Depot. That Moen brand of faucet is not the same quality as a Moen faucet from a plumbing supply house. Two different animals selling at two different price points.
I'm not here to upsell WDW merchandise, just pointing out what should be an obvious observation, but for whatever reason isn't.
I'd buy the Walmarts and use them. If by any chance they are lost or brake, WDW will always have the misters for you to purchase.
