Fantastic product… links right up to my cell phone. Use it to keep myself in check, but it's also a party favorite amongst my friends. Results are very consistent - you won't be disappointed in this purchase!
What's great about it: User friendly, consistent results.
What's not so great: Have no complaints at this point.
