1. The delivery was not next day it took 2 days. Not so bothered about this but it was the reason why I bought from Power button 2. The main problem I have is that I purchased a Sonos roam SL. The sound quality is good but the multi purpose main button is very difficult to use so switching to Bluetooth is very hit and miss. Also the battery drains on standby so when you want to use it it's very often dead. I also found the Sonos app often requires re-starting of my wifi router. I would like to have a refund for this item but as I had to open the box to find this out I do not think powerbutton will accept this. I would advise anyone thinking of purchasing a Roam SL to make sure they handle the product first and buy a charging port with it. Overall I regret buying this speaker but would shop with this company again Update - Powerbutton did deal with my issue very quickly and efficiently. I have now been refunded and just regret they do not stock other manufacturers as I would be more than happy to order with them. In my opinion this is a very good company. Thanks and good luck in the future. Steve
