Bought the VIB B-Tiger SPS Isofix child car seat for occasional use with our grandsons. Compared with similar seats from other manufacturers the VIB seat is very competitively priced and given that it will not get heavy use seemed ideal for our purposes. In fact, the seat looks well made, sturdy and durable and the isofix anchoring system worked just fine on our car, although a little more fiddly to attach than I'd expected. The seat with it's base is quite weighty and awkward to manhandle, so I wouldn't want to be constantly taking it in and out of the car, but I suspect this must be common to all of these multi-age group safety seats. The instructions are not great, basically very small diagrams that don't really show the necessary details (e.g. they don't show how the seat is removed, only how to install it, and removal isn't the reverse of installation!). However, it's fairly easy to work out what needs to be done, though best to do that before taking the seat out to the car!
