Just my review for Vu TV service , my friend had a issue of Powering On and off automatically and it took good 2-3 weeks i guess but they did cover it under warranty .So I m not sure of your mileage but in general the service is Okay ish but if you compare with the good brand standards its far off.
I've been using it for 2 years now. https://amzn.eu/d/9Q4xRdF. Maybe s/w support will end soon since this is an old model but I've been getting updates quite frequently. I think you should go for the newer if there is a hardware upgrade. Also even if this gets slow you can always plug in a fire stick I believe.
