... A high standard! Recently, I am also owner of the TS 850; though not on Amazon - may indeed times; o)) My vote is initially a first impression, since no long-term experience. Yes, the package scooter makes in "start-up" a very good impression: light, visually appealing, compact to store and relatively solid three looking. You could remove him that he delivers what it promises. A positive highlight, - Its working length of 1.10 m in the extended state, because hardly anyone has more to offer in this weight class, - Its solid die-cast aluminum shovel, - The curved central aspiration, - But especially the light Sperrbarkeit the wheels before folding while driving, - Why the previous model TS 800 commercially costs more than the "more sustainable" newer TS 850 still remains for me still hidden - Its light weight work. The rest is max. Middle class; so z. B. the wheels whose exact nature is concealed here and in most competitors partially or completely. The diameter is here 17,5 cm, the tire width 4 cm, the wheel center or the rim 14 cm and pressed plastic. Although ostensibly as advertised, so is the "staircase suitability" of the then only with max. 50 kg loadable cart questionable and with extreme caution to enjoy. 20 cm wheel diameter would be better to claim the advertising significantly to face! The accompanying bungee cords are only "first aid", complementary retrofitting seems imperative! The circumferential aluminum tube telescope system, including its Griffbereichsgummierung are moderate to minimum requirement. So much of my first "laboratory". Now you go to November to travel abroad with the thing, and then we know more.
