Changing meta title dynamically e.g. with number of reviews in title. Is this a problem?

I would like to put the number of reviews in the meta title of a product page.

I noticed that tripadvisor for example does the same. However I read in some places that people encountered problems with frequent title tag changes.

Did you ever encounter problems by just changing numbers in title tag?
Do you think it is really a problem if just the number of the reviews changes?

what about putting  number of reviews in the meta description instead?

Moosa, Martjin thanks a lot for your feedback.

So I will give it a try.

I absolutely agree with Moosa, used to do this before on a site where people could review services and it worked pretty well for us. As he already said, you don't violate any of the search engine guidelines as these are just your own titles representing the content of the page(s).

I believe if you are changing the title tag to enhance user experience then you should probably go for it and Google will also find it positive!

I believe adding number of reviews encourages people to click and chances are that the %age of CTR will increase!

I think you should go for it and this is because it does not really break any search engine guidelines and on the other hand it helps increases user experiences.

just my cents!
