I purchased one of Trinh's Blue Lasers and it is a very nice piece. Works flawlessly, and is great for what I need to rid my 150g and 90g of pests in them. Unlike a previous post, I like that it is machined a tad rough, gives it some character. Mine has none of the machining marks, it looks perfect.
Our transaction was great also. I would buy another from Trinh without hesitation. I hope this helps him for any other future transactions.
