Easy to assemble. Very sturdy considering no screws or bolts were needed. The only problem I had was that I ordered the wheel encoder kit to use on this chassis since the motors that came with the encoder would not fit the motor mounts in the right direction needed. No way to adapt them except to start modifying the chassis. The motors were DAGU mini with the gear drive at 90 degree angle. The encoder kit should come with straight thri drive with shaft extension for mounting the mag wheel. Will use the chassis for my next project. Cranes.

I was really looking forward to an improvement on the Magician Chassis so I could improve the summer camp that I help run, but this chassis turned out to be even worse. It takes a good deal of force to snap together (enough that I am not willing to bet my 5th graders could easily do it), and it is not modular what so ever because it is a pain to take apart, and you will most likely break pieces if you try (I did and broke a few studs, email me if you take it apart without breaking). Overall a disappointment, I'm not sure why it is so hard to make a decent chassis.

I brought the shadow chassis, so I could use it instead of the cardboard box for use with the Ardumoto shield kit. I am planning to use the shadow chassis with the Redbot board in the future since the motors will be already mounted

I bought the Shadow Chassis, some time back, to replace the Magician Chassis I had, and it has been a much better platform for building my robot. It snaps together much more easily and is a better platform to attach the Arduino controller with shields and breadboards for custom circuits. I was able to swap over the motors that came with the Magician chassis and I added the wheel encoders as well (you will want to purchase the motors if you are using this chassis, they fit everything perfectly).

My only issue has been that I broke one of the side struts when trying to unsnap things. Apparently you can't get replacement parts, so I created my own part as a replacement that can be 3D printed (http://www.thingiverse.com/thing:1196071).

I would recommend this chassis for anyone starting robotics.

My team has loaded two battery packs onto the chassis (one to power the arduino and one to power the motors) and no matter how we arrange them, the plastic piece a the front develops so much friction when moving that the wheels sometimes do not move.

This chassis has a big space to accommodate the processor, battery and others components to mount your robot. Easy to assembly and easy to use.

I had difficulty in assembling this thing. I actually needed to get my dad to help me to snap all of the parts in - I just wasn't strong enough (even though I'm an adult). It isn't just an easy "snap into place" chassis - it requires a lot of brute strength in my opinion. I have bought "snap-in to assemble" plastic kits before and in my opinion, this one was quite hard to work with compared to past experiences with plastic kits. After everything is assembled though, I'm confident nothing in it will budge even a bit. I mounted my Raspberry Pi, and it fit perfectly.

Also, one thing to note was that my fingers became black due to the material residue. (Not a big deal). You just got to clean your fingers after.

A good thing is that in terms of "real-estate" (a.k.a. the amount of space between the two plates), there is a lot of room compared to the previous Magician chassis.

All in all, I would say it's "ok" in quality. I recommend this product for anyone who is on a budget, and does not want to build their own chassis that can mount whatever popular microcontroller/computer they have (Arduino, Raspberry Pi, etc.).
