I was sent the silicone hoses without the couplers or clamps. These are useless to me. I emailed Jahvis Sawney to get my issue fixed. He asked me to send a picture of what I was sent and I did. Then it took him nearly a week to respond. It has been over a week now as I write this review. A few days ago I asked him to send me instructions for how to return the items since it had been a week at that time and there still had been no resolution, which tells me my issue is not a priority to UroTuning. They got my money so why bother rushing to fix the issue? Now, I haven't received any response on how to make the return. Very disappointed in their customer service and will not likely patronize their business ever again. Absolutely abysmal treatment!
