Yes, I would go for the link. Since this is a product review, getting a relevant anchor text link is totally appropriate, but be sure to mix things up when approaching other sites to avoid being hit by Penguin.
When evaluating a link, don't worry too much about domain authority. Having a high domain authority is nice, but just because you have high domain authority doesn't mean you'll rank for your desired keywords, and just because a site has a high domain authority doesn't mean the link is valuable.
Here are some of the factors Google looks at when determining the value of a link:
- PageRank (higher is better)
- Relevance of the site to your site (relevant sites are better)
- Relevance of the content on the page (relevant content is better)
- Total number of links on the page (fewer is better)
- Anchor text of the link (relevant is better)
If a site meets a number of the criteria above, it's generally a good site to get a link from.
