I loved Slizers as a kid and I still love them 15 years later. They remind me of the simple times of LEGO when all I did was playing LEGO games like Rock Raiders and Racers on PC. I wouldn't recommend it to anyone who didn't grow up with it, though. The sets look REALLY outdated. Roboriders, however, still holds up to this day.
I like the simplicity of the polybag Breez. It would be cool if they would release a line of smaller machines like that but a bit more complex and cost around €5. They could just be something to have on your desk.
Swede here. I remember this set being sold in some stores at a ridculous price of €8, a year later I found a bargain bin full of them for only €1. The combination of parts in this set are strange to say the least. It's just downright ugly.
