Nice size. Larger but not too large. Accommodates multiple plugs and plugs connecting at 90 degrees for outdoor Christmas lights. Met expectations for weather protection of plugs. The closing tabs could be sturdier. Exercise caution when closing not to damage tabs.

A little tough to close making sure all the wires are in the right spot and won’t get squished-but with the heavy rain this year, these kept everything dry! I bought several and none of my outdoor decorations were harmed with the electrical getting wet.YOU NEED THESE

I need to cover connections between extension cord and Christmas yard ornaments, and between ornament strings. The cords on the ornaments are attached to the SIDE of the plug (with an outlet on the end). I've tried several different extension-cord covers, but this is the only one that actually has room for ornament plugs without putting undue stress on the wire.

I have purchased multiple sizes of these to help install "R" brand plug in cameras on the outside of my house. I use them to hide the extra AC side of the cord as well as the transformer and USB side of the cord. I have purchased both the large version and the small versions. No such thing as a medium size. Hard to believe you have to choose between a tiny little thing or a huge ugly box just to fit cables inside. Looks like butt but better than having cables zip tied on the soffit hanging down.

Great heavy duty case to protect outdoor electrical connections including device transformers that are not water proof.Bought to protect a few connections for outdoor lighting.I would highlight that they are a good size for connections and single device tranformer. As long as your not trying to place a power bar that will not fit and see no reason to do so. And good heavy duty, you can walk on top of these without damage. There are other similar products for cheaper but doubt they are heavy duty as these are advertised.

I am using this to protect where two outdoor plugs connect from snow/rain. Comes with rubber shims which seem to give quite a good seal. So far so good!

I bought the Restmo Extension Cord Safety Cover, even though the price is a little on the high side, because the ratings were very high. We have a big hand held electric leaf blower that requires #12 wiring. If I had chosen a smaller safety cover (the ones that are for #14 wire and smaller) there would have been a problem getting the wires to properly fit. This device has a cam lock that prevents the cable from pulling back and causing the plug connection to 'break' or pull apart. The leaf blower has a cable that is about 18 inches long with a male plug on the end. The extension cord female socket is on the extension cord. The safety cover prevents the connectors from pulling apart while the blower is in use. While the setup looks a little strange (big green thing attached to the wires), the who setup makes use of the blower much more easy. In conclusion, if you are using #12 exterior cable, this product is likely to serve your needs.

I use this for my pool extension cord. We have had a few really big down pours and it kept the cord dry. It did let in a few drips but nothing that hurt the cords.

I used this product to secure the connection between a holiday light projector and an extension cord. I could not run the projector directly to the outlet as the cord was not long enough and the connection would have been in the middle of the front lawn and ground zero for snow and moisture. This connection box has rubber grommets on either side, and it comes with additional inserts in case you have skinny cables to make sure the connection is weather tight. It clips together easily, the plastic is sturdy, and has worked well for me so far. It is also large enough that if you have larger plug ends (common on some inflatables as well as some exterior extension cords) you should have room to connect them.
