Wobble Wedges

Indispensable.

Especially if you're a perfectionist about your TV and assorted electronica (satellite and cable boxes, speakers, subwoofer, AV control box, DVD player, ad infinitum) being perfectly level.

You could use variably thick small Post-It note pads, but then you're stuck with the colors of the pad edges peeping out at you.

Wobble wedges measure 1-7/8"L x 1-1/8"W.

The thick (and flat) end is 1/4"W and it tapers down to about 1/64" at the business end.

It's made of translucent plastic with small ribs running across it.

There's a hole to let you wear one as a readymade necklace or carry it on your keychain.

They're called Wobble Wedges because they "Fix anything that wobbles" but I've yet to use them for their intended purpose.

A nice review (and comments) over at Kevin Kelly's Cool Tools earlier this year nicely details the anti-wobble function.

6 for $3.49.
