I have spent over 10 thousands on parts, trying to do a return it won't let me for some sensors. I had 60 days and it is now 62 days. No way to get a exception, etc... Such a shame there is no way to get any support. The description on the site didn't say how many are needed so I don't think this was even a problem i should be responsible for. Going to loose my future business due to about 20 bucks.
