This Megazord was chosen by my eight year old son for his four year old brother's birthday. To be honest, I thought it was pretty over-priced initially (and still think it's a lot of money for what you actually get!)
That said, the toy is actually a 'transformer' style product which starts out as a large robotic figure complete with a rather flimsy little sword. My boys' favourite aspect is that the zord comes apart to recreate several other little figures. The legs, arms and head all detach and turn into animals such as a bear, turtle and a monkey. The unfolding can be a little tricky for a four year old's fingers as some of the fold out sections are a little fiddly, but I think the age recommendation of four years plus is fairly accurate.
Some of the figures are less recognisable than others as the animals they are supposed to be but they allow more than one child play together and recreate some of the scenes from the latest Power Rangers series. I suspect this works best with children with siblings willing to play together, otherwise the appeal of the toy could be quite limited once the novelty of attaching and dismantling the different elements wears off.
To its credit, the toy feels fairly substantial and is very durable (aside from the sword.) None of the main parts feel like they are likely to break easily which is fortunate as my boys can be extremely heavy handed. I would imagine that this will be in suitable condition to hand down to younger children or sell on afterwards.
If your little one is a keen Power Rangers fan, this transforming toy will be a popular choice. My four year old announced that this was his favourite birthday present so he certainly gives it a thumbs up!
