Bought 2: Garbage. Bike track breaks easily, the two halves of the bike body break when taking them apart. Hands to one of the spartans broke(both hands). 3 grunt hands broke, 1 of the broken is barely able to hold onto weapon thankfully. One of the grunt legs super loose when attached to body, and the head broke one of the neck joints as well. Even the assault rifle handle broke!!! DO NOT BUY!! UTTER GARBAGE!!! Positives: different version of invisible needler, and the little forerunner tower is cool.

The tread broke while I tried to build it... simply request and mega sent me a new one (two years later still holding perfectly). I did some mods to the side wall to add a missle launcher on the opposite side to the machine gun (which makes it even cooler). This is my favorite figures personal mode of transportation... who don't wan't a future tank bike :D.
The blue windshield is very pretty as well.

This was a good set, especially since I got an invis grunt out of it. I love the Spartan. The only bad thing is the tread broke in half after a while.

It was an easy set to build, however the turret on the side falls off often. The few parts holding the turret onto the bike are weak and often let go of the weapon. Otherwise the set is amazing and worth the price I bought it for.

The set was ok but the treads broke because of how stiff they were and how difficult it was to put them on. and scince it didnt come with an extra set of treads my siege bike was rendered useless.

Nice Set with Great design, loved the Spartan and guns. My only problem is the tracks because they were stiff and you had to push down hard on the bike for it to move. Apart from that It was a great set to build and nice looking. :)
