This is a great tool shed to keep a few outdoor items in so I don’t have to keep going into the garage when I’m doing outdoor work.  I put a couple bags of potting soil in the bottom to weigh it down. It was easy to get together.  I just had my 11 year old hold the sides for me to get the back on easier.  It works perfect in the area I put it. Sturdy plastic.  It won’t get much sun where it is so hopefully it won’t incur sun and other weather wears.  I’m sure you could put some silicon near the seams to make it super water resistant.  We haven’t had any rain yet, so I’m not sure if water leaks in.  I looked around a lot and Wayfair has the best price with free shipping.  All the big box stores around here aren’t allowing kids in with Covid-19, so I was thrilled with this.  It also came way quicker than they estimated.  Got it in less than a week.  Thanks Wayfair!
