First of all ... I am assuming that a score of 5 means Excellent ... which is the rating I would give my NN126 paddle boards ... I say boards because I bought 2. The quality is outstanding, the rigidity is great, performance as good if not better than any similar sized "non-inflatable", and the versatility is great ... in addition to the "stand up mode", we use them as "kayaks" with a seat attached (the seat from our Sea Eagle kayak) and also as a rower ... since I did add the rowing kit. Blowing the board up was easy because I used the electric pump ... it may have taken a lot longer with the manual pump, but I don't know for sure. As for portability ... I don't travel with them often ... but not having to have a Car Rack make this process easy ... outside of having to deflate and inflate. But less storage is space is big benefit. I certainly would recommend them as a Best Buy, and certainly would buy them again ... if I ever need another.
