That is not a make that comes too mind. Newer is essentially a marketing company so who knows who actually makes this filter.
In recent years I have only bought Hoya or kenko filters. They are two brands of the same products coming out of the same factory. They are branded as kenko in Japan and the east, and Hoya. In the west.
However there are a number of other high quality brands to choose from, and I am sure that you will get other suggestions.
Good filters are expensive, and at £29 that Newer one is on the inexpensive side for a 77mm filter, so I would not expect too much from it,, though the specification they give sounds ok..
