The quality and material of this lamp are a strong 5 stars! I can tell the clear switch is going to be reliable. There is an up close photo of that! 

Installation was very easy. Just make sure you take the white, plastic tightener off first. Place lamp shade down then add tightener then add your light bulb! It only took me 1 minute and it felt extremely secure. 

The only reason I gave this 4 stars is because of the size and price. This lamp is very small and for the price, I would expect it to be bigger.  If the price was lower it would be the perfect table side lamp in my opinion! (I posted a picture of it beside one of my other lamps so you could get an idea of the size). 

If you are not worried about the price and want a smaller lamp, this lamp would be a 5 star review on the material, quality, aesthetic, and sturdiness. Enjoy!
