So awhile back i bought all the bird 43 elements and a new hard case for them, sweet. I knew when i got them that they are all plastic now but wow, the quality is horrible. Yes its all plastic but not a heavy duty plastic, it is light and cheap feeling. The white top of the elements with the writing turned yellow from minor 85deg heat this summer in the mobile (under a towel, no direct light) And the worst part is, all the white plastic covers on the bottom of the elements are loose and fall right off, came that way new. If i dont make sure they are straight it wont even go in the line section. Totally unacceptable. Thats ALOT of money wasted. So reading the reviews and specs of coaxial dynamics element's, they are literally the same. Size, accuracy, tolerance etc. Except for one thing, they are all metal and brass, the white covers are glued in, they are heavy, solid, and look good. I just bought four of the 2-30mhz element's to check them out. Wow what a difference and the meter readings against bird element's? No difference. Needless to say i just ordered the rest of them and will be selling the bird elements as a whole. Sorry bird, i love and use your product line extensively but as far as the elements go, no thanks, im a coaxial dynamics guy from now on.
