## Ductulator Reviews in Соединенные Штаты

### *---- "Ductculator"
This new update version is not good they should go back to the original version!
-- don’ likeit, 2024-12-30

### ***-- "Pretty useful"
Comes in handy but limits what sizes you can pick. Not sure if it’s a bug but I wanted to see what my friction rate was for 16x25 and I can get the 16 but it skips from 24-26 and that happens often.
-- Aeco1195, 2024-09-18

### **--- "It’s ok at best"
Can’t punch in duct size to see what the cfm is very limited on what you can do save your money but it gives you different duct options if that’s what your trying to do
-- abc123abc bay you and me grill, 2024-03-07

### ***** "Don't be afraid to invest in this very useful tool."
Excellent application. Don't be afraid to invest in this very useful tool. The application perfectly meets its objective. I recommend it 100%
-- Enmanuel Sánchez Acosta, 2023-12-27

### ***-- "Needs work"
The new flex option isn’t working properly.
-- ShortMag270, 2023-10-27

### ****- "Let me reverse lookup"
Love that it gives you different options for sizing but I wish I could enter a duct size and get a cfm value from it.
-- ProbablyIan, 2023-10-26

### ***-- "No Flex in duct calcs"
Sadly, $2.99 spend, to discover it’s useless to me, without having the option to select “Flex” in duct calculations
-- Das Keep, 2023-09-25

### ***** "Options"
I love the App. It’s easy to use I just wish there were more options like selecting round or square duct as opposed to just only using Cfm.
-- AS2SCHLAX, 2023-04-07

### ***** "It’s a must have"
I get to retire my 25 year old Ductulator
-- Vic sr, 2021-08-06
