My first SUP experience with this board, so I'm a beginner. It has everything you need in the box. Initially, I thought the pump wasn't working (the pressure gauge) and I inflated it until the pump started to struggle and the board became stiff. That was my mistake and I can say that it was somewhat unstable in the water. With the help of a friend and the initial pump, we inflated it to the recommended pressure of 14psi, and the board became solid like solid plastic, so be careful with proper inflation.
Stable, enjoyable, and durable. It was tested beyond its limits (150kg) by 3 adult women for hours, a family of 4, 2 adults (each weighing over 100kg), and it came out unscathed. Even when it washed up on the shore with an 85kg rider, the fins remained intact (she didn't realize they were there and was trying to get back into deeper water, essentially plowing through the sand).
The paddle has adjustable tightening (to prevent sinking under axial load) by turning the latch that secures it.
It inflates and deflates very easily (with a button). Personally, I release a lot of pressure and fold it on the roof of my car for easy tying and minimal movement during the journey (6-7km from the sea). I can easily go up to 80-90km/h without any issues and tie/untie it in 5 minutes. It also helps with potential tearing from tree branches. Practically, it takes 5 minutes of regular inflation to reach its full pressure (it's super fast in one minute, but it needs to stiffen). I haven't used the carrying bag yet, but it generally takes up less space outside of the original packaging, so if you're traveling, it's better not to bring the box (it's good for storage during winter).
The only negative is that when putting it in the sea initially, the pressure may decrease due to air cooling (contraction), so it needs to be inflated and the pump doesn't touch the water or sand (it has a low air intake that needs to be completely disassembled, cleaned, and lubricated if it gets sand in it). So be careful with the cleanliness of the pump. Also, get a lithium grease spray to apply to the piston if you need to wash it or for maintenance.
It could be transported with a motorbike in its bag, but the process is more time-consuming.
Don't forget to rinse it with fresh water after use and obviously for storage.
Leaving it inflated in the yard, a cat sharpened its claws on the board... the board survived with some scratches on the non-slip surface. Now I leave it upright with the fins at the bottom to shade the cats.
