Raider 2.0 WITHOUT ETU
ETU has had some issues, can be picky on voltage,needs 11.1v to work usually
But the ETU units have crapped out on people (google or search on here)
They might have got them fixed now with ETU 2.0 arriving
But honestly get a Raider 2.0 without ETU - save £20 and possible headache
google G&G ETU problem/issue then decide for yourself
personally if your retailer was nearby then maybe worth a chance
if not I wouldn't bother taking the chance- you want a gun to just work, no gimmicks to go wrong
Just my own personal take - your gun, your money & all that
