Review on ⚡️ Zulkit 220X170X110 Waterproof Dustproof Electrical by Calvin Hodges

This thing looks like a mini Fort Knox! I am very impressed. I'm going to use it to store large batteries for my outdoor weather station so I don't have to go out and change AA cells every few weeks through drifts or whatever. I think the only unknown at the moment is how UV and sunlight resistant it will be. Otherwise if I make a good seal where the wire comes out of the box it shouldn't be impervious to anything. I also like the fact that they used metal hinges and latches. If you've read reviews of this type of box - this and other brands - you've seen the common complaint that they can be almost impossible when first received. open. This one was no exception. I couldn't open it manually. The seal is great and it can also be a bit sticky when closed at the factory before shipping. So, if the barometric pressure has increased significantly from the factory pressure, you may need to "help” open it with a knife or a thin screwdriver. If you handle it carefully and carefully, you can open it without scratching or damaging the box. I very carefully inserted a flat pocket screwdriver into the gap between the lid and case and slowly pushed until the air hissed and hissed. balanced the pressure. Thereafter the tackiness of the seal was easily overcome. Then, as another reviewer suggested, I put a very thin coat of synthetic grease all over the seal and it's much easier to open now. It's still responsive to changes in air pressure (which tells you how good an inflation really is), but it's a lot easier to open. Verdict: Not cheap but I really like it and I highly recommend it.
