Page Sizer doesn't even work. It wont even verify my email to start changing the page size. It stinks and its not worth the time or the money. good luck to anyone else who gets this. After reading other people's reviews before installing it, I thought they were all just makin things up. But then when I got it and experienced the same thing, I realized they were right. Mark my words Its a waste of time. Its a complete joking hoax

You have to pay to use it, and it doesn't even let you adjust things unless you break through that pay wall. Not really the kind of ad-on I want to use for my google docs that I just want to use to print somehting small - since google itself doesn't let you adjust page sizes enough, I was hoping that this would do the trick.

Monthly subscription required for something that Google should have provided a decade ago. What a joke.

This product is great! It was very easy to use and I no issues at all. I also emailed Yam about a question I had and he took care of it right away. 5 stars all the way through for the product and customer service.

It does not work! I had a horrible experience. I had a deadline to meet and quickly needed to resize a document. However, once I paid for this add on, I immediately received an error message and only automated systems when trying to hunt down support. A total headache. Now I'm hoping to get a refund. This is horrible! Error Message:Error: ScriptError: Authorization is required to perform that action.

This did exactly what I needed it to as I was trying to make a custom size for my google doc before submitting to Amazon KDP. Yam was very responsive via email and helpful to cancel the subscription as I no longer needed it after.

I had difficulty getting the app to recognize my ongoing subscription. I contacted Yam and the repsonse was immediate with several back and forth analysis. Yam had it working within minutes. The best customer support experience ever!

Scam. Only after installing and asking for permissions does it notify you it costs $2.99/mnth. Sure, maintaining software takes effort, but that's exorbitant for such a simple feature.

The page resizing works, and the developer was able to add other Page Setup options to the extension so that you can also set margins and a background color. For now, you can't do anything else in the original Google Docs Page Setup once you've used the extension, which is a bummer because for my project I need the ability to set different options for different pages (different background colors, mostly), and I can't do that with the extension. I had previously posted this review saying that the extension breaks Page Setup, and the developer responded within 24 hours and had added more options, which is awesome. It still won't quite work for my project but is a great tool as long as you only need one set of page-setup options for your entire document. A lot of the low ratings seem to be because of the cost, which I think is unfortunate. Developing extensions does require labor, you know! I'm updating my review to 4/5 because it still doesn't have quite all the features I need, but it's a good tool.
