Radartest is not an unbiased organization. They sell their data to companies to use. They approached Valentine about selling them test data and they refused and ever since radartest has slammed them. If you check their data you will see that it's incorrect or misrepresented to slight the v1(such as weight or dimensions) I've had my V1 for 3yrs now and it has saved my ass too many times to count in that period. The only tickets i've had in the last 3yrs(2tix) were from airplanes that CHP uses here in cali. Get the V1, it's hands down the best.
