I ordered the RASER+ together with the Gunprimer Gate Remover Set and the results you achieve with these are great! Nub marks can be completely removed without any traces left if you don't put stress on the plastic by cutting too close to the part. Regarding the price, everyone has to decide this for itself if it is worth it, but to me it is.
The delivery from Gundam-Store.dk was very fast and safely packed as usual.
