Ah I see. I did feel some of them were rather weak though (but like you, I don't want to derail this thread)
As for the 2017 sets:
Ultralight Helicopter: I think this is "meh", but for the price ($29.99 in NZ), it's tolerable. It's the same price as the Stunt Bike & Truck in the US though, so that's not so great.
Stunt Bike: Kind of "meh" too, the exposed gears to power the rear wheel look bad and make the bike too fat. Plus it's $34.99 NZD so, since it's much smaller than the equal-priced Stunt Truck, it really hurts this set. I would buy this only to get the combined model.
Stunt Truck: For $34.99 again, this has great value plus the color looks great. What's not to like?
Roadwork Crew: $39.99 (same price as Scarecrow Special Delivery) The models themselves aren't anything overly awesome but I think they work. I like this set.
Telehandler: I like this set, but the B-model seems lacking and it's $59.99. Ouch.
Container Yard: I like this! The reach stacker looks cool and the truck seems nice as well. The stacker seems to grip the containers pretty well. And I like the B-model too!
BMW: Eh, looks a little crude in its final form. For $99.99 (same price as Container Yard) I'd skip this in favor of the Container Yard.
RC Tracked Racer: This is $149.99. Crazy! I understand that there are Power Functions but the final model looks pretty small. I could buy the U-wing for the same price and be much more satisfied.
Ocean Explorer: Seems pretty good value imo ($199.99) but there are a few flaws with the design, as I learnt from @Sariel's review.
Air Race Jet: The functions are awesome, but for the price ($269.99) I feel there could be more.
For the summer sets:
Airport Rescue Vehicle: Looks pretty interesting, have we had a similar vehicle in Technic before? Though I probably won't pick it up
Extreme Adventure: Not a fan of how it looks. Purple and black can go well together, but not when mixed with grey and yellow.
Tow Truck: Hey, looks cool! But I wonder how long it is, since it seems a little small for the price (thanks Power Functions?)
