The ports are slightly wider than they are supposed to be. Installing the feet and legs will damage the ports on each figure.

I really like what this set does to add to it's aesthetics in size and looks real feet and hands. While the size of the Guns are a bit too big . They Definitely Weight too much! The boots used as arms can not hold the guns up in a sweet pose.. which moving the figure could help...but why should it need to be done. Materials used are good and color match is spot on.. over all good.. just short of "Perfect"

This upgrade was totally necessary to give Abominus proper size hands and feet. The hands and feet that come with the potp terrorcons are just horrible.

I personally like the redesign on Abominus for potp with this upgrade. I like the execution of Hun-Gurrr. I do miss the dragon head knees a tad-

PE does it again! They provide very little at an over inflated price. A simple recolor that adds darn near nothing to POTP Abominus.
Whatever has happened to make PE so proud of their offerings needs to be re-evaluated.

While this kit WORKS as far as providing Power of the Primes Abominus with functional hands and feet, it is a very low-effect attempt on Perfect Effect's part.

The hands are straight recolors of the hands created for Power of the Primes Volcanicus found in PC-21, while the feet are similarly-colored reuses of the feet found in PC-22 for Power of the Primes voyager Starscream. The included guns are black recolors of the guns created for PC-10, meant to be applied to Combiner Wars Bruticus.

Unfortunately, due to a combination of recent re-engineering on Perfect Effect's part and reusing parts created specifically for different toys, this upgrade kit does little to improve Abominus. The individual figures that comprise Abominus cannot easily equip the hands or feet when transformed into their gun configurations due to their unique hands, nor is there any way to store the large guns when not in use as they were originally meant for Combiner Wars Bruticus' back. The kit sadly does not include any parts to mitigate Power of the Primes Abominus' structural integrity issues or improve its poseability. The switch from ball-jointed ankle joints to weakly ratcheted swivels as of PC-21 means the feet parts are basically unnecessary, as the stock feet included with Power of the Primes Hun-gurrr can accomplish the same level of poseability, if not more.

While it is the cheaper of the two upgrade kits created for Power of the Primes Abominus, PC-21 feels as though it does not give you your money's worth, especially when compared to previous efforts on Perfect Effect's part. Functional, but not recommended.
