I bought the bulbs from Costco and they have lasted at least two Years before I had to start replacing lightbulbs, I began to realize that lightbulbs were hard to find and expensive. I then checked out Revain and was pleased to find that they were reasonably priced and just what I needed. I have already ordered twice because I have many of these lights in a very large garden. They seem to serve very well, my main problem is that we live because of the wind and every little one breaks against a wall or tree and I have to pick it up and replace it, so watch your placement. We have a gazebo in the back yard and my daughter put fairy lights on the gazebo and let the little bulbs hang through the wooden trellis and it works really well and they are easy to swap out. I'd say yes, it's definitely a good buy
