Its great for me since when i started. They gun itself is well made. Solid and tough enough to get into fire fights. I used this gun for a long time switching between spyders and other clones but i always came back to my gt.
The stock is so crap! and the grips were even worse. A bit heavy but if you stretch ur arm it all works out. Plus if you cant handle the weight then ur a weakling...no offense lolz!
Overall this is the best out of all the spyder clones and works with all uprgrades which i like to do... =P The price is well within range and fixing the basic problem is breezy.
