Imaginext- any good?

[TheHAUNTEDHouseofMirth]

Despite my best efforts DS1 who is nearly 4.5 has recently started watching commercial tv and now wants every toy known to man. He is especially taken by the Imaginext rocket, submarine and fire engine. They look a bit prescriptive to me and given the choice I'd rather get him more Playmobil or Lego but wondered if anyone actually had some?

Obviously not then...

We have the firestation and engine, I think it's pretty good. Well made and not too flimsy and the plus side for us is that it has less fiddly bits than playmobil (ds1 is only 3) as my 2 tend to lose all the bloody parts.
