### 1/5 — Waste of money

*2021-07-13*

There is nothing on this app apart from conversion charts and p&id symbols. To make it even worse, the pages are photo copied lol

**Developer response:** We provide the same pages from the hard copy of the Pipe Fitters Manual within this app. I'm sorry that you feel free is a waste of money.

### 3/5 — Torque Tables are missing

*2021-06-16*

I have used TT hard copy Pipe Fitters Manual for years. I use the bolt torque tables extensively but they are missing from this digital version.

**Developer response:** Look under Dimensions of Welding Fittings and Flanges >> Torque Data.

### 5/5 — Great!

*2021-01-23*
