Gear: Playtex Straw Cups

What is it?
Playtex Lil Gripper Twist 'n Click or the Insulator Twist 'n Click straw cups
How does it work?
Simple twist-on lid with a soft upper straw & integrated valve that doesn't leak. Transparent cups (or insulated with cute patterns) with a 'waist' to make it easy for little hands to grab.
Why is it good?
Easy to take apart & wash. They make a variety of interchangeable lid types. It really doesn't leak. You can find replacement parts online & upgrade your lids without having to buy the whole thing again. (Update 5Feb2012: REALLY annoyed to discover that I can't seem to find the parts online anymore, now that I want to buy a few. Grr...) They come in a variety of colours so you can tell them apart. Also, the First Lil' Gripper Twist 'n Click Straw Trainer Cup doesn't have a valve & you can squeeze a bit of water or milk up the straw to show your child how to use it the first few times. These cups seem quite durable too: after being chucked on the floor & sidewalk countless times, the large ones haven't broken. (One of the handles of the small cup did break off after repeated chuckings however)
Where can I get it?
London Drugs, Superstore, Shoppers Drug Mart, online.
How much does it cost?
$5-6 each.

*I didn't get any freebies from Playtex to write this review. My sister recommended these cups & Sprout's been using them daily for about eight months.
