I am new to the forum and really enjoy the dialogue here. I have purchased 3 lasers from Lazerer with no problems whatsoever. In fact , I use a 1.2 W 473 to routinely fry Aptasia in my marine reef tank. Works like a charm. Last month I purchased a 300 mW orangish/red laser from Lazerer, but unfortunately it arrived DOA. I immediately made an attempt to procure an RMA. Tried 3 times but received no response back. Question? What's with the seven day return policy. What a joke! Seven days to return a defective laser to hong long from SoCal? I'm done with Lazerer! 100 bucks down the toilet. Once again, I really enjoy this forum. Be careful where you buy your lasers...
