Maybe I am late, because you already ordered, but I would recommend on Lazerer actually.
I have had experience with both O-like and Lazerer.
I bought three lasers from O-like, two were underspec and one died a short while after it came. I had to return all three of them, two were replaced and one was refunded.
O-like's customer service was medium. Not replied to all emails, and I had to nag them for replies, but eventually they sent me good up to spec lasers, and refunded me for the dead one.
As with Lazerer, I bought three lasers from him. All of them came very fast on regular mail. Two are overspec, one was underspec and was refunded.
Lazerer's customer service is excellent. All emails replied within one day. Immediately refunded me to my request for the underspec laser and didn't insist on me getting a replacement.
All in all, I think that Lazerer is a better company than O-like.
