Dear kg, Thank you for viewing. Easy to install, just screw it into the ground. It rotates 360 degrees, so the wire won't get tangled and it operates smoothly. Convenient for outdoor activities, camping, barbecues, picnics, etc. I bought it to enjoy the outdoors with my dog. I used it for my Shiba Inu (10 kg), and it worked comfortably without any problems. Used only once. It's still clean and usable, so I hope someone will find it useful! Please check my profile and thank you in advance.
