There are a few complaints such as the suspension wheels being too loose so they dont stay on the correct side of the track which causes the tank to not move as intended. That is my biggest problem with the tank, the other problems aren't truly problems, but rather just me being nit picky. There is only one other thing I can think of, I have the tank built and put up in my closet on a bin because I have nowhere else to put it out on display sadly, and I went to grab a new shirt and I accidentally dropped it and it fell directly onto the barrel and broke it off. At first I thought "man I need to click that in better," and when I pushed it back into place it just fell right off. Upon closer inspection the tan peg had cracked I assume that when the shirt hit it that was the cause of the fracture, but that was my fault and I already replaced it with a black Lego brand peg, so all is fine! As for the build process and the condition of all the pieces, figures, and weapons, I am very happy with my purchase! The Tiger tank is just remarkable, I was so overjoyed when I got and put it together, I ended up taking it apart just so I could rebuild the set again, and it was just as fun as the first time! I honestly think that anyone who enjoys Lego and WWII era tanks, they should get one if not more of these to amass a huge collection. Thank you I plan to buy more tanks from here in the future!
