I was specifically looking for solar lamps that come with a 3 inch diameter pole and these are advertised as such so I bought them (based on two answers from the company and the product pics). However, when I received the item the poles are only 1.25 inches in diameter and the top mount of the light is screwed into the pole and does not contain a collar (also as shown). I reached out to the vendor and they were very responsive and exceeded my expectations so I ended up keeping the product. Even though they aren't exactly what I was looking for, the lamps and poles are well made and sturdy and they work as advertised so I've decided to keep them. Overall good buy for the money.
