A really good knockoff i found

 I looked up galaxy explorer on Amazon and stumbled onto this set

I was surprised at the quality of the bricks.  The 2x1 brick feels slightly lighter than a lego but the clutch power and fit is really good.  This wouldbe great to make a classic space model.  Even the rod elements were straight without warping.  The translucent yellow pieces are handy too.

Favorite non lego set

 I have found 1 non lego set that I really like.  I love the colors, the multiple building options. 

It makes me think of the designer set 4096 from lego.

I think it is a clone type of set resembling lego style.  "Oddly" the set numbers are 4096 lego and 6409 kazi.  I don't think it's coincidence that the numbers are similar.  I can't definitely say it's an exact clone but I put similar model pics from lego

Above is the kit I think was cloned

Here's the non lego set I like:

The model below has different hubcaps than all the other pics ifbthe set so unsure whether or not this is a clone.

I can't tell if there are clones because the hubcaps are different 

Also there are 7 models but the ad says 5 in 1

There is a good video on you tube showing the construction.  I just like the wheels, colors  and multiple building options which Is like old lego boxes with

Multiple building options 

I want to try making this out of lego

Again, I think the Kazi model is loosely based on the lego set in the first pic of thus blog.  I do like the color scheme in the kazi. But the quality of lego just beats any competition
