Heist X7 bike

Was just in Go Outdoors and they had a clearance Polygon Heist X7 for £300
I can find little on line in the way of reviews, but it seems like very good value at that price, especially as it seems to be exactly what I was looking for for my youngest (school run plus tracks and trails though not anything that rough)
I've been looking for second hand but nothing has come up
I've only a basic knowledge so I'd appreciate any advice and thoughts from those that know more!

Thanks in advance
Phil
