A new short slider have emerged onto the market, the Neewer 30cm Slider which also can be made into skate dolly. With this slider being only 30cm, you can easily keep it attached to your tripod without having to take it off, as it won't take as much space or be quite heavy compared to other sliders that are 60cm long or even longer. Also being just 30cm long it would fit easily into any camera bags.
