Been going to get a copy of this for while and now I wished I'd brought it sooner.

Handy size.
Good range of data.
Nice quality

As others have said, a bigger version would be nice ( A5 or even A4) for the aging customer!

For a quick reference guide it is what one would differently want to have in his/hers collection.

Book is well informed and displayed out nicely.

Understand that this book is made to fit in your pocket. It would be nice if a large print book was also made.

All the main go-to information in a clear and well presented format.

Good Sturdy pages, nice layout

Could benefit from cuttaways for easy page turning like some other volumes.

Great addition to any workshop

Nice and concise with every bit of information you could ever need.

coated paper and ring bound is a great idea

Best engineering book by far has lots of useful information on anything you will come in contact in a work shop, easy to read and understand.

Easy to read, easy to use, invaluable bit of kit

Pages become easily dirty could laminate them ?

Great source for commonly used information normally found in the Machinery Handbook.

Wish I'd discovered this book years ago. It's great to have on hand, and a great refresher for a lapsed mechanical engineer like myself.

Pages are a little hard to turn. Bigger spiral binding would help there. An option to buy a version with bigger print would be great too.

Great condensed source engineering data in a small convenient package

simplified data and equations

pages are filling out binder rings making pages difficult to turn

Great practical reference source

concise information clearly presented

could benefit from thumb tabs or cutouts for different sections

Very handy reference book for mechanical trades.

Absolutely amazing so handy to have, has the information you need right in the palms of your hand.

Great content, lifesaver, quality feel and durability

Wish they made a complete book with all the other black books combined.

Easily the best little book full of information wouldn’t be caught dead without it

Too much to list it’s fantastic lays flat, pages don’t mark easy

I’d probably buy another one if they came in larger page sizes

Great book couldn't live without it now

Whole book

Nonoe

The content of this reference manual and the quality of the printing is astounding. Great for looking up small details that sometimes slip the mind.

Well-organized and easy to read text and graphics. Nice little drill point gage included!

I once tried to look up screw thread engagement rules of thumb, and didn't find it. That's OK, in order to keep the book short (and lightweight), attention must be focused on the more general content. No biggie!!

So much info in a small book

Well organized

None so far!!!

Great form factor for shop queries. Incredibly dense amount of information. I suspect it won’t replace all reference books but it will certainly become my daily go to

Full of lots of useful information, in a very handy size. Perfect for the workshop

Great book

Easy to use

None

Having so much information handy in your pocket is a great thing

Page material
Bonus drill gauge
Good index
Quick conversion factors on back cover
Pocket sized

It's gonna take me a long time to read
