We compared two 4D shiatsu neck and shoulder massagers: the RENPHO Neck Massager and the KNQZE Neck Massager Cordless.
What we looked at
Power source, heating technology, and price.
The verdict
If you want a household power adapter and car charger included for use anywhere with a socket, plus a lengthened 2.5m adapter cable, the RENPHO is the pick at £35.99. If you would rather pay £11.48 more for a fully cordless design with a 2500mAh battery and graphene heating technology, the KNQZE is the alternative, at £47.47.

A £35.99 massager with both a home adapter and car charger included.

A £47.47 cordless massager with a 2500mAh battery and graphene heating.
