Diesector:

Like all the Battle Bashers, this one is well designed but does have some differences from its real-life counterpart. I pretty much do the same thing with these as the Battle Bashers but to do that, I have to remove the "gripper" on the end.  For one, when right-side up, its wheels don't touch the ground. Second, after removing the "gripper", his wedge doesn't touch the ground, nor does it "flop over" if he is inverted.

Grendel:

I'll admit that this one is very well designed, except that the weapon has nothing to pull it back up, so to speak when you remove the "gripper".

Tazbot:

If it weren't for the large hole that was left over when the "gripper" is removed, I'd say he's very well designed, his weapon can rotate(doesn't seem to rotate 360, though), though his front wedge doesn't stay on very long.

Toro:

When the "gripper" is removed, his flipper doesn't stay low to the ground and his sides keep lifting up. Nevertheless, a well-designed Grip N' Grappler.

Mauler 5150:

This one is very well-designed! Very solid and sturdy construction!

Ziggo:

Like Mauler, this one is also well-made! The armor doesn't seem to stay on well, though.

FrenZy:

Unfortunately, I think this is the worst designed of the Grip N' Grapplers. Neither it's armor, nor its axe seem to stay on for very long.

Deadblow:

Here is another well-made Grip N' Grappler! It's wheels touch the ground and its weapon really works and also pops back up into position!
