Review: Proper stuff, sorted my dryer out! - Finally got round to replacing the rubbish old ducting on me tumble dryer, the old one was practically made of cobwebs and hope. This AC Infinity stuff is a different kettle of fish altogether! It's really sturdy, you can tell its got those four layers they talk about. Was a bit of a wrestle getting it connected up, like trying to tame a shiny silver python, but once it was on with a couple of jubilee clips, it felt solid. The 8 feet length was more than enough, had a bit to spare. Dryer seems to be working more efficient now too. Well chuffed.

## Questions & Answers

**Q: It seems like the bad reviews are about size and come from march of 2020. Did you switch manufacturing or something? If so had it been resolved yet?**
A: The problem was, it just said it was 4" in diameter, but did not point out that the 4" were outside diameter. The product itself is probably good. I needed an air vent hose with 4" inside diameter, so it can go over a pipe with 4".  I wonder why somebody would be interested in the outside diameter for these hoses anyway. 
I ended up buying a non insulated hose at Home Depot, where I could take my own tape measure to see with my own eyes what I am buying.

**Q: Has anyone else noticed that none of these are actually 25ft in length?**
A: I had to send mine back, because of the diameter was not what I needed. There was some confusion, I had thought it would fit on a 4" connection, but it did not. So, I bought something else at a local store, where I could physically measure the ID.

**Q: Can this be used as an hvac supply duct?  (heating and ac)**
A: If it can be used for a dryer vent, it CAN be used for HVAC , the dryer produces more heat that a home furnace.

**Q: Come in white??**
A: Hi there, 

Thank you for reaching out to us!

I'm sorry but we do not have these available in a white option. 

Kind regards,
