Excellent Excellent SERVICE Excellent Excellent SERVICE! Any issue or question and they got right back to me....even a phone call too! AND The unit works GREAT! Easy installation with instructions provided. Perfect size/performance for my 144" Sprinter 2500! It's really "COOL" now! ;-)

Good product and solid customer… Good product and solid customer support. Our 2000R unit worked great on four 100ah lithium batteries. Install was a bit tricky, but got good answers from the support guy. Looking forward to the housing extension for thicker roof installations.

NOTE WELL the return policy!! The builder's opinion is that the unit is too heavy for the roof of my particular van. That is not Velit's fault. What I did not expect was the only return within 30 days if it does not work return policy. I did not even think to check the policy because...well, who doesn't have a 30 day return policy for an unopened box? I take responsibility for not checking, but I find this policy completely unreasonable. Now I have a $1700 (including shipping) unit that I cannot use.

Great service with great products Great service with great products! I love my gasoline heater so much, and look forward to the future updates for this and for what else this company has instore in the future!

Great Purchase - I recommend this product Most importantly: The heater is working great! Keeping us warm on cool nights. It pumps out significant heat. I live at an elevation >9000ft. So far, this unit is working great whether we’re heating the van at home or while traveling. Also important: Post purchase support was great. I broke the electrical connector that the unit ships with and they shipped me a replacement no questions. Highly recommend. Well worth it considering alternative gasoline units are 3-4 times the cost.
