I was researching on this and found a lot ppl give good review / thumbs up on their FB Page. Probably incentivised, but seems okay so far.

Only issue I had with them is their showroom in Penang so got nothing physical to check and “test” build quality. But they got installer in KL so no worries on that.

I end up going with Avant smart/digital door lock instead since got showroom in KL (Mt Kiara) and overall combo pricing is cheaper than Abrain.

I got the main door + grill door combo for RM2299. There’s a member referral for Avant, discount RM50. Can pm me if you keen then I can pass you my name for the referral.
