Just bought 55u7a from Desa Home at RM 3000 inclusive of (3+2 year) warranty. This price is much cheaper than what HN is selling. Initially was tempted by HN offer of 55A6501 at RM 2500+ with (3+2 Yr) warranty. The 55u7a price at HN was RM 3300+.Then saw Desa advertised in Shoppe the higher grade 55u7a at 2599. After chatting on line decided to go direct to their outlet at One City to see for myself. The display of 55u7a looked much better than other entry level 4K TV at the same shop.
Tv is installed and viewed with its standard setting. The HD & 4K content looked sharp and colour saturated. Will try to play with the setting over the weekend to try to try to get the best visual.

There is a u7a Owners thread at avforum. Many owners seemed to have problem with their sets and need to update their firmware. But generally it received good feedback.That prompted me to get the additional warranty

Just take note that the 55u7a TV stand is as wide as the TV, which is close to 120cm. Have to get a new TV bench to fit the TV as my original TV bench is only 90cm.

1. No local apps.
2. Have not tried. I have tv boxes connected to to the TV, so no need to install apps to TV.
3. Wirelss connection is painless. Netflix 4K is smooth.
4. No Astro. I have not tried Astro go or others, as the TV still new and I don't have much time to play with the TV on weekdays.
5. I watch movies thorough TV box.
6. I think so but I don't do mirror content so never try. Plus the TV box already come with chromecast.

The extra warranty insurance cost slightly more than 400. Initially the shop assistant also quoted higher price but I told him Desa is advertising the TV at shoppe for 2599 and ask if they can follow. If the shop does not sell at 2599 for standard warranty, you can still buy it online and arrange for self pick up if you want to or wait for them to deliver. That's was my initial intention. However the shop assistant said can follow the on line price so I requested to buy extra warranty and finally settled at RM 3K.
