Rented an SRM powermeter from CycloHire for a time trial I did in May. Was delivered with UPS couriers, with a bottom bracket. The staff were very helpful and the powermeter was very useful, even if it only told me how weak I was!
I still managed to do a PB. The SRM was recently calibrated and matched my TACX turbo trainer well.
I had arranged and paid for courier collection to return the item and they had included return labels, which I just stuck to the box and UPS collected the parcel on the date requested.... All in all a great company and some useful products.
