Over the years I’ve had 2 garbage disposal units installed by Despo Japan, in both our house and our new apartment in Tokyo. I’ve also installed one by myself (DIY), which I ordered from Amazon - that turned out to be a big mess. The installation, service, and choice of units offered by Despo Japan make it a huge bargain and great value compared to DIY. Despo Japan’s stuff works great and no hassle or worries and they are experts - I highly recommend them!! Thanks to them for the excellent service and value over the years - couldn’t live in Tokyo without it !!
