EVPAD Plus is stable at both.
EVPAD Plus is using 2GB as it is very good in loading the product. It won't lag when switching channels, exit App and open App.
EVPAD UI is easier to use. EVPAD have separate App for different country live TV Channels.

As UBOX only use 1GB RAM as it may lag. My friend used UBOX 3 then 3 months later all channels cannot work already.

Ubox not all channels are stable. Some channels cannot load for a week or more.

I suggested you to get EVPAD. EVPAD is the best top recommended TV Box.

I'm getting EVPAD Plus soon in 3 weeks.

Thanks

You're welcome bro.
EVPAD is suitable for your dad. As it has user friendly UI.
Easier to navigate through.

EVPAD have KODI installed. You have to install it manually.
If you want the KODI loaded. You may buy from the seller who will install KODI add-on for you.
Yes, nowadays many Apps need more RAM to load. That's why I recommended EVPAD PLUS.

UBOX is not really friendly, difficult to navigate.
EVPAD have separate App like Taiwan Live, Malaysia Live and etc.
UBOX doesn't have. All in one App. Difficult to choose if you want to watch which channel based on the content.
EVPAD have more content and more channels than UBOX. I don't suggest you UBOX as this box is super unstable.

Make sure you buy it from Authorized Dealer.
Must ask for the things below before you buy.
1. 1 to 1 exchange warranty
2. 1 Year Warranty
3. Money back guarantee within 7 - 8 days.

Before buying, look for certificate.
In FB, look in Photos
In 11street, Lelong and Lazada, look in Product Description --> The Certificate name must be the same with seller ID. Some seller copy and paste. Some of them put the certificate that doesn't match with the seller ID.

Original Price as below:
RM 760

Promo price --> RM 700 - RM 760.
Below than that consider as blacklisted product. Except during promo sales.

You have any more questions, you can ask me more.

I haven't got the unit yet. Later I will get it as for now my house TV and Cabinet haven't fix yet.

I have studied a lot about EVPAD and UBOX. UBOX last time famous then now no more. Now is EVPAD more famous and IPTV more stable.
Thanks. Have a nice day
