Nokia phones are always trusted for their great build quality phones.
Nokia 109 is a great phone in terms of build if you are a rough user and you need a device mainly centralized for voice calling and sms go for it because no brand in the market can have the quality of nokia devices.
There are many phones available in the market with same functions or maybe more functions than this device with less price but they cannot be trusted but you can always trust nokia brand for their build quality so my recommendation is to go for it.
