Walk in coop was good value for money.  Parts were a little banged up from shipping, but nothing a plier could not fix in minutes.  Have patience and take your time.  It will take a day to assemble it well.  It is well thought out and end result is good.   No missing parts.  No assembly problems other than minor dings & dents on tubes.   You may want to use your own tools and not those supplied for ease of use.  10 mm wrench and Philips screwdriver required.
