MJJC.com has mixed reviews regarding its legitimacy. On Trustpilot, the site has an average rating of 3.3 based on two reviews. One customer reported horrible customer service due to a lack of tracking information and unresponsive support. Another customer found the site easy to order from and appreciated the good payment options, though they noted the lack of shipping information.
In contrast, Auto Care HQ provided a detailed review of the MJJC Foam Cannon Pro V2, highlighting its super thick foam and adjustability. The review mentioned that the foam cannon produces thicker foam than most alternatives, but it also uses more snow foam, which could increase costs.
On MJJC's own website, the foam cannon has a high rating of 4.90 out of 5 based on 3,935 reviews. This suggests that many customers are satisfied with their purchases.
Overall, while there are some concerns about customer service, the product quality appears to be well-regarded.
