We use Pitney Bowes at work. Certainly won’t bother renewing/replacing when the time comes.
Consumables are heckish expensive for the small machine. (cartridges were circa 90-100 last time I looked) I seem to recall someone in our office worked out that if you only sent first class letters, by the time you paid for the print cartridges you saved about £5 over the life of the cartridge vs stamps.
You pay a flat fee for topping up the meter as well as your service charge so it only makes sense to top up a relatively large amount at a time.
The machine is infuriating to use and very slow. Ours loses the WiFi commonly enough its now cabled. It still fails to connect to the service center for top up, rate changes, data uploads etc seemingly half the time and won’t let you process post until it does, sometimes days later.
Having worked at a large institution where the machine sealed sorted and franked it saved a lot of time and effort, for a small user I’m not at all convinced. The only benefit is the convenience of not having to buy stamps.
