Long lasting high quality product  Time owned: more than 12 months
I am happy to made one of my best decisions 8 years ago - I purchased an Optibeam OB8-4M!
So my dream of having at least a two element yagi on 40m went true.
This antenna has the same perfomance today as when I got it new in May 2003 as the first one in field. It is sturdy and survived heavy winds.
Due to its Moxon design this 4-Band Yagi for 40/20/15/10 has a footprint of not more than a classic fullsize 20m Beam.
If space is a concern and you would like to play the game on 40m you should put this antenna on top of your list.
It is amazing if you rotate it and get nearly 20dB F/B while pulling the DX out of the noise or get that punchy signal to pop out of the crowd.
On 40 I often log the DX after the first or second call. Two elements even make the difference to the majority of callers.
So the decision 8 years ago IS one of the best I have made.

I'm still in heaven  Time owned: 3 to 6 months
A quick update, the antenna is still working great, infact its that good i've took to working qrp to give me a challenge, still working dx on legal limit but also working 2k+ miles on 10watts, its a real dream.
