I don't know how this price will change, but right now we're talking about incredible value for money.
It comes with its base. The top box locks when you close it (with a spring), so when you put things inside, you simply close it and leave without wasting time. In other words, you only use the key to open it. It saves you time, but be careful not to leave your keys inside and accidentally close it, because then opening it takes some effort. It's made of very durable plastic, and there's a rear reflector which is also good quality. It locks onto the base with a screw from the inside, and the system is very good. It doesn't have a passenger backrest cushion, but its shape is comfortable and won't be bothersome if the other person leans against it. It fits one full-face helmet lying on its side. For use on a small motorcycle, moped, or scooter, I think 28 liters is enough for everyday use without being cumbersome.

Excellent and high-quality top case. I installed it on my scooter and it makes no noise at all, unlike the previous Kappa one I had. I highly recommend it.

Easy to install and secure. With one screw that you remove and insert, you simply take it home or to work for safety

Well, at €26, the first impressions are excellent, it fits a Large helmet with minimal space around it, obviously time will tell how long the lock will last, the color compared to the more expensive Shad and Givi, but for 1/3 of their price, this one is value for money!
