Previously, we used cheap connections that always came loose and leaked gases. Since we have switched to Superlok, we have had no issues of gas leaks. Their products are high quality with good prices. Wren has been very helpful with our orders, always sending updates on the status of our orders. I would definitely recommend Superlok.

We called Swedglok; the manufacture of the German end of the problem. It took 30 minutes to figure out what I was needing and to find that it will take a week to get it. I called Superlok. Wren knew right away what I was talking about. She had the solution in stock. During the exchange I needed to call her a number of times to up the quantity or change freight to early AM delivery. Wren was easy to reach and I felt her smile from my end of the phone. Good companies are made Great by the staff they employee. If this was an interview, I would hire Wren.
