My reason for 3 stars. Received it yesterday and it was not difficult to put together. We had a big rainstorm yesterday and I found that water is getting inside the unit.  My main purpose for ordering this unit was to keep gardening supplies safe from moisture i.e. tools, soil, fertilizer, grass seeds, etc. This morning I laid a large trash bag over the unit to hopefully keep the rain/moisture out as it is expected to rain off and on over the next few days. I did notice that the door of the unit does not shut flush which is why water is entering the unit. Our old unit (20 years old) which was beginning to crack and fall apart did not allow water/moisture to enter. I should not have to cover the unit to keep moisture/rain out.
