This was posted a couple weeks ago, but the OP messed it up by including an additional expired rebate. $25 is a good price for the Oral-B Pro 1500 (like the Pro 1000, but with a lithium battery).
Lowest price on Amazon in the last year was $45, and this rebate is better than the $15 Oral-B rebate from December.

It reads like a legit Slickdeals rebate, but if someone knows how to vet this further, it would be appreciated to include in the wiki. Thanks!
