sharing my limited knowledge:

all 3 brands are from China.
Fotile is the premium brand. Robam is very common, generally used.
Livinox is new entry to Malaysia market- doing a lot of promo, giving a lot of incentive to reseller.

Fotile is very established in Malaysia- after sales service should be ok.
Livinox since they are pushing hard- would expect them to set up aftersales service there after if they have enough market presence.
Robam... no comment from me as i just come to aware this brand recently.

on selection... at the end, it is just a blower, actually very little tech on it. but of course they market with all the sensor, automated flap etc.

i will just look for the highest flow rate (1800m3/hr above consider higher) and lowest noise level ( below 50dB)

on design- new launch would be the slanted glass panel. it looks very sleek indeed. but one of the "honest" salesman share with me.... do you think the panel will remain clean and spotless after cooking? or you want to spend time wiping it down?
do you it to do work for you, or do you want to work for it? Lol.

anyway- i will go for those traditional flat/square type.

yeah, i will probably get Fotile 9035 Hood and FD2B Hob
package price is 3700 RM

it is 1950m3/hr with 48dbs

if there is any other alternative, do share ya

Cheap, Powerful and Quite, Reliabile.
