generally speaking my experience with the conglomerate.
Aftershock PC <--- (cheap and value, service has been awesome, annual free dust cleaning) Great Service, will recommend. very flexible, everything can chamsiong.
Aftershock laptop <---- (2nd hand laptop, even out of warranty, they replaced the keyboard FOC for me, and annual free dust cleaning). Great Service, will recommend
Secretlab chair <--- arm rests started rotting 18months into use, the PU leather start to fall off bit by bit 24months into use. shlt product, will not recommend.
MASH.sg <---- custom keyboards, this one also at their boon keng showroom, so dunno if they are same conglomerate. their keyboards are good, but usually if you know where to get from taobao, you will be able to get at much better price for the exact same product.
omnidesk <--- i dun have any of their products, friends have, all very satisfied with it
Prism+ <--- got a gaming 165hz x 1080p x 27inch monitor before, cheap, no problems, great colors once you turn on the HDR setting. Sold it off after 3 years as I upgraded both my monitors to 1440p from gigabyte for the KVM. Surprising thing is, the prism monitor has more vibrant colors compared to the new monitors i bought.
