For $200 you can't beat it. I had a Burris AR132 which was bigger, heavier and more expensive, I sold it and bought a SPARC.
Really like the dot. Glass is clear. Feels nice and sturdy. Comes with various attachments so you can customize the mounting height. AND it comes with a 2x zoom attachment.
Even has a NV setting (meaning it can be used in conjunction with your other NV optics).
Mounts easily and has brightness settings.
You can't beat that for $200
Pros: Inexpensive. Clear. Simple. Sturdy.
Cons: None
