  1. Review by Buzz - Great transistors, great price. verified purchaser

    Transistors arrived still on their ammo strip. I like that... same batch. Clearly labelled in an electrostatic bag. All good, thanks. Great pals with the 2N3906 (PNP) these are great transistors to keep in stock, very versatile and a good alternative to quite a few other transistors. (Posted on 1/03/2013)
