I purchased Tiki 4 pack wood pack to enjoy a backyard famiky gathering and I couldn't be more pleased! Super easy to use, just light corners and viola! Each Tiki wood pack had a burn time of approximately 30 minutes while burning evenly and no mess. I love that the entire wood pack has been made from bicycles sawdust and burns clean flames. If you are looking for a low smoke, low smell and low ash then this is the perfect product for you. You can sit and enjoy your beautiful, warm fire without worries of adding wood/kindling continuously which allows you to really relax and engage with family and friends. Easy storage as you can store anywhere. I recommend Tiki Brand Wood Pack and will continue to use this product myself. This is an amazing value for a great high quality and effective product. Tiki Brand wood packs do not leave an excessive mess to clean up either; ash was at a minimum at the end of burn time. 
The above stated opinion is 100% that of my own.
