I think the only reason one to not go for it it's the price
Now I'm comparing Arxtech/optima, panther, renex and solidmesh, the one with good quality and best price will get my money.

I just went to compare arxtech and panther. One thing i noticed is the amount of airflow restriction these mesh gives out. It darkens the house significantly and although both looks very solid and safe, but i feel it makes the house dark and reduces airflow (chi). Decided to give it a miss and use only the Optima windows, door etc. Will be giving 3kim a call this week

Did from 3kim too.

1.2mm - rm18
1.0mm - rm12

yo, I actually shortlisted panther and arxtech after some comparison (though just surveyed 4 suppliers in total).

All produce quality products, but personally, I like panther for its mesh windows' function and features....n yea.... only mesh window..... For arxtech, their mesh window is not bad, wif some thoughtful design too..... together with optima window, more choices n style....

If i only nid to do mesh, wud go for panther..... 

yea, in the end have decided to go with optima & arxtech for the balance of mesh and window..... due to the varieties of window they r having.... n more choices on appearance..... 
(Also mom like their winblind window for kitchen.....  )
due to mco, now not sure when will be my renovation starts.....

Actually it's better if you could provide the dimension of your window and get the quotation direct from them, cause sometimes they got promotion ongoing.
I just got my unit installed with Panther and would rate 4/4.5 out of 5 for them

For deluxe mesh casement window around 105/sqft before 20% discount, and to get 20% total order before discount should above 15k. Got the deal before metal price is increase, not sure if they still having same promo not.
1. Edges of mesh frame are quite sharp if without sanding it, it's not that difficult so I do it myself with a sandpaper.
2. Some screws found below mesh frame part are not smooth to the frame surface level, not that obvious though.
3. There's still some tiny aluminium residues found at installation area even they had tried to clean it with their own vacuum.

Already give feedback to their sales so hopefully they improve those I mentioned in future, anyway quite satisfied with their products which give premium look and safety.
