Review on 🛋️ Black 20mm Round Heavy Duty Nail-on Felt Pads: Furniture Leg Floor Protectors for Smooth Sliding - Set of 40 by Rashid Summers

Some issues with these. I have used sticky protectors in the past but since they leave a sticky substance when they need to be replaced I decided to give these a try. However, they are difficult to install without a pilot hole. Nothing is provided or recommended in relation to instructions for doing so, and nothing is included to create a pilot hole. If you step on hard wood, they bend. Hitting too hard or too hard with a hammer will cause the felt to go flat. I suspect this will shorten their lifespan and I had to use more parts than expected. Worst of all, when they don't walk straight, the chairs shake (like in my case).
