Product names tend to be constant even when vendor names change. What Reviews Can Do In general, product reviews are very useful in narrowing the field of possible products. Reviews can also point out product strengths and weaknesses. While these are often not significant to the big picture, some of these strengths and weaknesses may directly bear upon your proposed use for the product. For instance, if you see a great hard drive, but it's SCSI only, and you only want EIDE drives, such information helps you eliminate that particular drive from consideration.
Reviews can flag an excellent product.
If reviewers from multiple sources uniformly extol the virtues of a particular product, that product generally is one of the leaders in its field. Reviews can, but rarely do, flag a poor product. Poor products generally can be detected by consistent lackluster reviews. Cannot Do Product reviews cannot select a product for you. Invariably, a person can use reviews to narrow the field of contenders to 2-5 products.
