I'd do it properly, get proper hosting and a proper domain, it'll only cost you <$20. Free hosts are shit and their nameservers are spammed of the face of the planet, you're asking for an easy ban.
You can review one product on the homepage and call the website product-review.org or whatever is available. Heck you can call it barbieworld.com and it would still rank if you're going to rank it with spam.
You can then compare it with another product on the page, just to increase your conversions a bit although it's not necessary.
If you're going to do a complete comparison and multiple reviews, you might as well make it an authority site and not churn and burn
