It is easy to get caught up in the marketing hype about something new, especially if it could solve an important problem or satisfy a special need. However, I have had enough disappointments when things have not lived up to expectations. More recently, consulting on-line product reviews has been a big help to avoid these surprises. However, care needs to be taken since they cannot always be taken at face value.
When product reviews are based upon early samples, they may no longer reflect the current product. Bad reviews may then no longer be accurate since problems have been fixed after the review was posted. It is therefore very important to make sure to take into account the date of a review and make sure that it is current especially if it is a bad one. Otherwise, the downside is that benefits from a truly good product could be missed.
