I was looking for deep reach clamps and decided to order Wetzlers, in spite of several posts indicating people had a difficult time contacting the company, some orders arrived weeks or months late, and some questions around the company's viability.
I had a different experience and just wanted to add another data point. I ordered the 9 inch quick clamp, mostly as an experiment, on Wednesday, November 4, from the Wetzler website. It arrived today, November 6, from PA to MD so it was likely shipped the day after I ordered. On a different note, I did reply to the email confirmation asking about shipping and it went unanswered, although I'll take the silence and the next day shipping.
I can't speak to the company's overall health, but ordering from Wetzler worked fine for me this time and I'll be adding a few more. Oh, and yup it's a rock solid clamp.
