Head Massagers in Cyprus: Do They Work, and Which One Should You Choose?

After work, I often feel tension in my head and neck, especially after spending a long time at the computer - and then there’s the heat on top of that. I’m thinking of buying a head massager, but I’m not sure if it actually works or if it’s just a way to relax for a couple of minutes. If anyone in Cyprus has used one, please let me know - does it really help relieve tension, or is it better not to waste money and choose something else? And which type is better: a simple manual one or an electric one?
