Review: Worked exactly as intended. - For the past 30 years, I've used insulated ducting thinking it was more economical to keep the furnace heated air hot to the adjoining mobile home. I was very wrong. Rodents would chew through the plastic of the insulated ducting which let much of the furnace heat blow under the home rather than into the room it was intended to heat. Once I ran out of the large quantity of that insulted ducting, I gave in and forfeited the insulation to purchase these ducts. Probably the best decision I've made regarding my heating in those 30 years. I expect these ducts to last the next thirty years. I had this ducting installed last winter. It has now been a year since these were installed under my mobile home. For the first time in decades, I haven't had rodents chew through my ducting and running up and down the main vent. I am impressed with the quality of the aluminum used. (It doesn't appear to be porous or have voids.) I also found the corrugation to make the flexibility feature just right for the 90 degree turns I needed to make. The size is accurate and the duct fit easily over the mating parts.
Review: Great product - Should have started project with this before wasting money on metal duct. Very easy to work with and solid material.

## Questions & Answers

**Q: Can this be used for pellet stoves**
A: Can take a small amount of heat and is made well , probably could be used up higher if insulated, or for feeding . Tube is rigid when bent

**Q: Whats the max length it will stretch to?**
A: I found that it will stretch to about half of the length stated.  Even this much is difficult and must be done very carefully.  The pipe is made of very thin material and has been compressed by creasing.  Stretching can easily tear the pipe along the creases.  It may be possible to stretch it further, but only after practice and experience.

**Q: Is this safe to use with my undermount 600 cfm range hood?**
A: I would say yes.  I used it for a 400 CFM range hood and it is working well for past 2 months.  The material is malleable so it will bend and conform to different shapes but still hold its integrity.

**Q: is it really flexible or semi flexible**
A: It is very flexible and thin compared to a dryer hose. It can make a 180 degree turn and fold back on top of itself with virtually no gap left on the hose.

### ⭐⭐⭐⭐ very strong and flexible easy to work with
*by J***D on October 2, 2016*

This product arrived early and the packaging was very well.the price was my main motivator. I bought this for a grow tent i did not realize how ridged these are totally not what i need with that said its not a bad product but if your looking for something that bends easily this is not it it is also loud when using ducting fan so if this your intention i would say try something a little lighter not a bad product quality construction just not what i needed my mistake not the companies.i ended up using this for a bathroom project i did and it worked beautifully for that project It was easy to work with and cut very easily as well as retains its shape nicely.it is very durable and lightweight and easy to work with if you are using this in this type of fashion i would definitely recommend.
