This should and neck massager is quite portable so I could easily bring it with me on short trips (comes with a typical wall plug for power but also a car plug!)
Things I like about this is that it is easy to use yet it is very effective. I love the fact that it has various intensity levels so I can change between them depending on what I feel like. I also enjoy the heat aspect of it, which makes the entire massage much more rewarding after a long day at work.
However, the only downside that I would have liked is some sort of battery pack included such that I don't need to always have a power outlet to use it. If this was improved this way, I would be all over the moon. Nevertheless, at this price point it is something that is well worth it.
