Pros:
✅ Cantik. Seriously aesthetic. Especially the 14/10 model although not everyone can accept green-white combo.
✅ Gentle on clothing. Washer dryer both treat my clothes very gently compared to other mid range machines I've used before.
✅ The heat pump dryer means the area doesn't heat up like normal vented, but it's faster than normal condenser dryer. Claims to be more energy efficient (from my monitoring, it's sort of true but depends on your clothing material whether quick dry or slow to dry)
✅ Cantik, the smooth matte exterior very aesthetic.
✅ LG thinQ app is nice to use to control/monitor the washtower remotely. Phone will notify you when a cycle is complete. You can also custom make your own cycle, remotely control the cycle, start/stop remotely etc.
✅ The dryer got smart function where it matches the preset of the washer cycle, so no need to do complicated setup to remember what preset you used before.
✅ Cantik. Just really nice looking 😍
✅ Super duper quiet. Don't hear the drums vibrate and spin like in normal washer/dryer.
✅ Space saving and more user-friendly to vertically-challenged people compared to stacking seperate dryer on washer 😬 because all the controls are around 90cm from floor, for both washer and dryer
✅ Did I mention it's cantik?

Cons:
❌ MAHAL GILA NEED TO SELL FIRSTBORN CHILD
❌ For the price, you can get very premium washer and dryer separately that can perform equal or better. All the above fancy functionality you can get in separate machine (except for the synced cycle presets)
❌ As you concerned, the machines are housed in one casing. They are technically two machines put in one case while sharing one control board, but if one side rosak then it'll probably be hell to replace
❌ Seriously, super expensive for what you get.

In my personal opinion and as a buyer, only buy it if you cannot afford space to stack separate machines/want a sleek look AND can afford to pay the premium price tag. The premium is in the appearance design and the combined functionality, with a bit of space saving.

In terms of pure function vs value, I don't think this is a good choice.

If you rather have more direct control over maintenance and have the space, buy separately.
