Customer Reviews
Good cannon, slow shipping
I ordered the MJJC S V3.0 Foam Cannon and a Karcher K-Series Adapter. The cannon itself works really well, produced thick foam just like I'd seen in videos. Setup was straightforward. My only real gripe was the shipping time; it took almost 8 days to get to my place in Ohio. I've had faster deliveries from other detailing sites. Customer service was fine when I inquired about the delay, but the tracking wasn't very detailed. Overall, happy with the product's performance for the price, but they could improve on the delivery speed and communication.
Always reliable MJJC gear
I've picked up a few items from MJJC over time, and they've always been solid. Ordered another Pro V3.0 Foam Cannon last month because my old one (from them too) finally gave out after years. It shipped out quick, took 4 days to reach me in California, same as my previous orders. The quality is consistent, foams up great with my pressure washer. Good to know I can count on them for detailing stuff.

Hey, anyone know how long shipping usually takes for these? I'm in Dallas and wanna get this before a trip next month for my car.
Thinking of grabbing a Pro V3.0 but totally new to foam cannons. Do these things actually work well with regular pressure washers or do I need some super high-end setup?
