Unreliable - Hex Hex Wasp Micro Red Dot Sight

I bought the Wasp because I could install it on my Hellcat myself. The Wasp made it easy to qualify even at 25 yards, but It stopped working after two months. Springfield replaced it under warranty. The second one stopped after two months. Springfield replaced again under warranty. Thank Goodness for the co-witness groove, at least that was reliable. A friend bough a Romeo for his Hellcat at the same time I bought mine. He has had no problems. I went with the Wasp because it was easy to install. The Romeo required grinding down screws. Wish I would have went with the Romeo.
