This kit is well designed, manufactured, packed, and delivered. Minimal defects in the wood components. No issues with dimension or pre-drilled holes. All joinery hardware came with spares. The included tools, specifically the phillips driver attachment with an overdrive barrier, was thoughtful and appreciated. Reading directions is a definite requirement, but not difficult to follow if you take your time.  When beginning the build plan for 25-40 hours of work and check the weather. A tarp in case of rain is handy.  A good 20-24volt cordless variable impact driver makes this much easier. Only improvements I can imagine would be a weatherstrip seal for the door and an overhead LED shop light. But these were easily added. Overall, great value for the price. Much nicer than any prebuilt, and cheaper than any comparable unit i could find.
