Not Absolutely Necessary - But Get it Anyway

I purchased the Hansgrohe 27169001 Chroma Green Showerpipe and it requires precise placement of the stub-outs. You could make your own template, but this makes it idiotproof. You cannot misaligne the stubouts using this metal template. If You're going for upscale and a lasting product, spend the money so the install goes without problems. Granted, I think this should be included, but it's not. Oh well, just figure you're spending a tad more for the fixture and live with it.

expensive for something that should be included but easier than downloading ,etc.

There are just things that you need. This is one of them. By using Amazon & Prime I get more choices, a better selection, and don't have to run around wasting time and more money

It does what it says! I didn't really need it though. If you need it it works!

Get for what I need it for. If I made a living with it, maybe not.

Didn't need it, but it sure looks good in my Computer, and that's all that counts

You don't actually need it if you only use it for common use. It is too complicated in function

not all you need, but good to learn some basics

It's not too much of a big deal. But it's ok.

This is a good reference to have especially if you don't have internet access. However, I wouldn't say it was a necessary purchase since there are so many online references now that give the same information for free.

Not much to add here except a vote and my strongest possible recommendation . Essential

Yeah, didn't need this because one came with the printer. Shrug. I'll have it when the first one runs out in a couple of years I guess.

Nothing special, but it serves it's purpose.  Sometimes it's just about convenience, and to have this delivered instead of having to go shopping was worth it.

Essential, but you do not need to pay $450 for it. Find it at Michael's web site or elderly dot com.

If you know what this is, then you know how well it works and how there is pretty much nothing else to replace it.  If you need it, buy it, and if you don't need it, buy it for someone who does (before they stop making them!).
