Dom - I thought the same thing, but turns out they are well worth it, for the base, and the refills are very well priced. I've got two of the biggest refillables.

My last order was for 6 refills if that tells you how much my macs love them!

Josh.. You are definitly older then your years.... I thought that movie was so cute...... Short Circuit it was...

Older than my years? Johnny Five is classic!!! Its funny though, cause I own that movie and just the other day I forced my girlfriend to watch it.

Mine in Syncronized playing with the refillable SS base toys...

I see this several times a day....

Some days they're hanging from the toys... others they sit and chew :-} This video actually isn't all that exciting (or clear, sorry) but it shows just how content they are with their toys.

That was really cool Dana... Thanks for sharing....
