Callidus (or “Callouses” as spell check tries to make me type!) fulfilled my order quickly and efficiently at a very reasonable price. What’s not to like?
Great company , paid online , they let us know it was being dispatched next day and what day to expect delivery. Well packaged and super service 👌
Highly recommended, fast and efficient delivery
Nice kit but could really do with some help with the rest of my build 😁
It’s an amazing inverter easy to install and powerful.
Shame they wouldn’t deliver to Northern Ireland. Had to be imaginative
Great piece of kit, excellent value for money (purchased while on offer) great delivery even though we purchased between Christmas and New Year.
Being installed next week
