Double strollers of higher quality and with a low price tag are not totally compatible. It's bugger and to be high quality, it takes quite some costs to make. The Evalite Duo is an ok buggy, but mostly that, a buggy for more occasional use. Not totally sure I would recommend it for a little baby. but 5 months old could actually work - IF you're ok with a very simple stroller.
I personally would look at the [valco-baby-snap-duo|Valco Baby Snap Duo]] which is superb for the price, however I don't know how available it is around you. Another option I would check would be a pre-owned Baby Jogger (either City Mini Double or City Mini GT Double) which is roomy and sturdy and nice to push.
