    Default Review- Cobra ESD 9870.

    Also in response to Brick's request for more cheapie reivews:

    The Cobra ESD-9870



    This was the 3rd detector I owned. I bought it after returning a ESD-9210 becaues of all the POP mode hype.

    Basics-

    Audio- Tones were distinct, in fact pretty similar to the Bel stuff. While they would almost get loud enough, it was somewhat distorted on high volumes. (remember I have a whole different definition of loud than most people, i'm sure almost everyone would find it adequate). It's louder than the 9210, but not as clear.

    The display is so-so as well. It had a nice text display with a good menu system, but bright sunlight caused it to be pretty hard to read, since it was a yellow display.

    Mount- Didn't ever rattle, but wasn't all that stable. Fell off now and then. Here's a pic-

    The little rubber feet kept it from rattling, but the detector set back off the window a ways.

    The 9870 was a long unit, so it did wobble around some.

    Misc-
    Cord needed to be longer. It was a coiled cord, and really, had it been a standard cord it would have been long enough, but it didn't seem to stretch much without pulling the unit off the window.

    Performance-
    K-Band performance was pretty good for a cheapie. Even from the rear it was pretty good. It might have had a little trouble detecting distant instant-on.

    Ka was pretty good in town, but on the highway, the warning might not have been enough in some situations. While I was never able to verify it myself, supposedly the range to the rear on Ka with the 9870 is horrible.

    Laser was nothing special. Even mounted low, I went right through two laser traps with not so much as a beep, but they were both close range, so I don't know that anything would have alerted.

    Pop mode falsing was simply unbearable, and when POP was enabled, standard Ka falsing went way up as well. It was un-usable with POP on, no two ways about it.

    Durability-
    Died after a few months, but it was left in the sun too much and fell off the window too many times. Cobra did send me a brand-new XRS-9700, so can't complain.

    Very interesting reviews! I think the 9870 is the one that I see constantly around here and I've always wondered how they perform.

    Around here the 9210 is extremely common. It used to be sold at Wal-Mart, so they were everywhere. The 9210 looks a lot like the 9870, it's just a bit smaller and has a cheaper display.

    That could be it. I never see them from the display side. I just see the case which looks just like the one in the picture.

    Here's a pic of the 9210.



    It has 4 buttons on top while the 9870 has only three.
