The worker was very kind and helpful in answering all my questions & getting me set up with my unit. The 5x5 appeared to be more like 4x4 but I didn't measure. Due to size, I opted for a larger unit which resulted in a higher cost than I had planned. I also opted for an outdoor unit which is effected by the elements causing the latch to rust and often stick making it difficult to open. I would suggest that they start replacing these before they rust shut & need to be cut open. I also found it uncomfortable that the gate is so slow it allows entry without a code by followers. I'm not sure that can be fixed- just unfortunate. Overall the facilities were clean, well lit at night, tons of security cameras, & very friendly staff.
