Ill be honest im not one to leave reviews but when I do come across genuine companies I do express my gratitude as I run a business myself. I bought the disk and when I received it, it was great. No issues at first and I definitely was saving on charge. I have a model 3 long range btw. Within 2 weeks the caps to the disk fell off while driving and when I informed support they instantly sent me a new set of cap with 0 ring rubbers I believe its called and they do snug alot better. I didnt ask for them to do this as i wanted to see if i made a mistake with them while installing them so I know not to do it again. To anyone getting these I would recommend getting the 0 rings caps with your purchase. Those caps do not snug on the best without them. Definitely recommend this company and highly appericate there accommodation.
