Washer and Dryer 2 in 1 Combo

Hi all, was thinking to get those 2 in 1 washer dryer, but have some mixed feedback, some sales told me those 2 in 1 wont never dry the clothes, you still need to hang for a while, some say only Bocsh high end able to dry and some say all brand should be ok. Although i think it should dry but just want to confirm here especially those who uses 2 in 1 washer dryer. 

So Bro and Sis, my question is, if i purchase those 2 in 1 washer dryer, and i didnt overload the clothes. 

1. Will if dry as in we can just fold the clothes after it done the washing and drying ?
2. Roughtly how long it takes for washing plus drying? 4 hours?
3, Please also let me know your 2in1 brand and model if possible
4. what is the pros and cons of 2in1 ?

Thanks all !
