Sadly,  I ordered four boxes about 5/6 weeks ago, to make a nice size dog run, im still waiting for two boxes as they keep getting damaged in transit. Ok so updating my review, i have finally got my last part of the order today Nov 28th. on the whole a good product, flexible, not sure how it will overwinter as I have made an outdoor run with 4 sets.  I would have liked the door catches to be a bit stronger.   but this works well for my Engish Cocker Spaniels. updated, it wintered very well.  re the door catches my dogs have never got out, so they are fine.  I'm changing to 5 stars as I am really quite impressed.
