We hesitated a lot between this version and the newer, more expensive than ten euros, mainly because in the more expensive version, it was well noted that there would be a guide strap on the shoulder. This accessory seemed to us very interesting. Having finally found that 40 euros (with shipping), it was all in all a bit expensive for an inflatable booster seat, we finally ordered this first version to 28 euros. And were therefore extremely and pleasantly surprised to see that the famous strap guide that allows to position the belt on the shoulder, was included! We are very happy with this purchase.
