Great red dot - SIG SAUER ROMEO5 1x20mm 2 MOA Red Dot Sight

I have a Holosun HS503bu but wanted another red dot and wanted to buy the Sig Romeo 5 since the Holosun won out the first time I was choosing a red dot. I like the Sig better, why? The battery is way easier to change out and has a big knob not a tray that can easily break and can be opened by hand without tools. The sight was perfectly sighted to a 25 yard zero so I haven't touched the elevation or windage. The only thing the Holosun has that this doesn't is a 65moa larger circle that can be activated. But for $100 less than the Holosun I would definitely buy the Sig Romeo 5. It's home is on a 45° mount on my ArmaLite AR10 and the Holoson got mounted to a Glock 21 Gen 4.
