Plug in Doorbell (Stockport SK3)

Tecknet Doorbell with two plug in chimes. This works intermittently so we changed it, both plug ins have multiple chimes and is quite loud, it may be useful for putting in the shed/ man cave to call your other half in for his dinner?? I will be around after 12.00 tomorrow. Please do collect if you say you want it, it's very frustrating to have no shows.
