I was not going to write this review but got an email asking for it. So here it is. Usually, I try to focus on the positive, maybe this will help the company improve.
I have the Guzzle Stealth, and it is a great product. I had to replace the UV light and filter casing because they froze during winter as I had not winterized it properly. One of the collets was broken on the quick connector of the sensor. I emailed their contact address [****] 4 times to see if I could buy a collet and never got a reply. Finally, I bought the cheapest part they had to get a collet out of to resolve my issue.
Ideally Guzzle should have a contact phone number for support. At least respond to emails asking for help or information.
Support is a major factor when customer decide what vendor they are going to buy from. If someone asked me about the company I would say great products bad support.
Again, I love the product, just need better support.
