Focus mitts are great tools to use when training. They help with conditioning, technique, and drills which help sparring.  The only thing you need is someone knowledgeable with pads willing to hold them for you and train with you.  There are plenty of advantages to using focus mitts, such as:

• Learning to block
• Improving and developing footwork
• Accuracy
• Combinations
• Conditioning and Endurance

I would highly recommend using focus mitts in your training if you currently do not.  Developing your striking game is not only beneficial for the ring or cage, but also if you ever need to defend yourself.  Train hard so that you can fight easy.
