I have bought Intermatic and RedDot brand cases and they are easier to work with than any of the others. The depth is incredible. I use smart plugs and USB chargers in my outdoor outlets and they seem like the cheapest and very deep caps to me. Other brands don't seem to offer this deep coverage, and I can't seem to get others to work with my devices (which also have bulky ports). RedDot is a more durable product. The locking of this product is a little weak compared to RedDot. I would rate the durability higher than Intermatic.
