I truly wish I had checked out the reviews on RVupgrades.com before making our purchase. The UV filter unit arrived with two 2" holes in the inner box and the outer box was split open. No worries it's just a box, right? Upon closer inspection you can see broken glass inside the UV filter housing. The main unit was just rolling around inside the box without any bubble wrap or padding. No wonder it was damaged! I emailed them about the damages, I received no response, so I called the next day. They'd have the correct person call me back; this didn't happen. I called the following day and the same person was out to lunch, uhg! Finally, we synced up with emails and a phone call. They wanted pictures of the damages before they would process the claim and provide an RMA. I explained that the damages are about 9" down a 3/8" hole and a normal camera can't capture the damage; I had already tried. Pictures of the damaged shipping box wasn't enough. With this reseller provided stonewall in place I told them I'd contact the manufacture about the problem. Acuva understood the damage I was talking about and agreed to send a replacement unit right away. Wow, issue resolved via a couple emails! RVupgrades.com, don't walk away, RUN!
