I have been using them for over a year. I am very happy and offer a lot of value compared to competitors. I was using a friends log in for vauto for a while until they caught on and kicked me off. I was shocked at the cost of vauto and a wholesaler told me about laser appraiser. They are very similar and i think the vin scanner actually works better on laser appraiser.
Message me if your interested and i can send you a sign up link
I've used Laser Appraiser, Autoniq and Accu-Trade. All serve their purpose and LA is better than Autoniq, but Accu-Trade is my choice. You can tell it was built by dealers and has everything you'd need from a demand/supply, pricing and scanner. Their auction price estimate is freakishly impressive...it takes into account common vehicle issues, damages, etc. I feel like they offer 3x more than the others at an extra ~$50/mo.
Just my thoughts though. Sometimes simpler is better and you can't go wrong with Laser Appraiser.
