Investing in any one fund depends on your risk appetite and time horizon. Hence one cannot give a standard advice.
Having said that, this fund has been an average performer in the value category. You can consider this fund along with one or two funds that complement in style (such as a multi cap fund or a large cap fund) based on your goals.
When you invest, ensure you only do in Direct Plan variants of the Mutual Funds. You then get upto 40% more in long term portfolio size by avoiding commissions and brokers. If already invested, then switching to direct is really easy.
