I just got the first six Microns come in and I was a bit skeptical at first. But I had a lot of fun putting together. There were times when I was scared I was going to break them (Gundam never had joints like these) but I had a blast.
These are way better than the capsule ones as well! Those joints kept popping off.
To put it simply, for only 8 bucks a piece I basically cancelled my pre-orders on the capsule toys and went and bought duplicates of the ones I would totally use in uncombined form.
Finding new ways to combine these guys is also part of the fun. I can't wait to see the Arms Microns they will have for the Weaponizer Optimus (2 known, 3 to go!)
If you like putting stuff together or improving on things (Thanks Reprolabels!) This is what you need, total 80's fun!
