They seem to be good and I hope they last. Maybe I could give them four stars. I used two of these to build an elevator to access storage under a trailer bed. My only complaint is that they have a slight difference in extension and retraction speed between them, which makes me wonder about the quality control in production. If they prove durable I would give 4 stars, maybe even 5.
