Amazing out of the box, shoots super straight with no "whiny" gears, build time was extensive however for this product it requires more work to be done due to gearbox edits. Trigger response is amazing. The bluetooth option for the Titan 2 (Expert) is handy if you're looking at statistics related to battery drain, or if you want to change what each selection does on the selector switch. Perfect for indoor AND outdoor use depending on BB weight.
The only downside I have to this (and most) AEG's is the ambidextrous selector, I am a left handed shooter and the L hand selector is INCREDIBLY tough to move, so it's easier just to use my index finger to swap through selections.
In the box contains the gun, PTS EPM, A Matrix 11.1 battery, and a Titan 2 patch along with the other smaller essentials.
