Jared Newman reviews the Hisense Sero LT 7in tablet, currently selling for $99 in Walmart:
But there’s one big caveat with the Sero 7 LT, not listed on Walmart’s product page: According to Engadget, TechRadar and others, this tablet will only last for about four hours on a charge. Most other tablets last at least twice as long. Even if you’re not planning on hours of consecutive use, a big battery allows you to keep your tablet lying around for days at a time, using it on and off throughout. With a four-hour battery, you’ll need to be extra mindful about plugging the tablet in when it’s not in use.
Also, keep in mind that while the Sero 7 LT’s microSD slot compensates somewhat for the measly 4 GB of built-in storage, it’s not a cure-all. Some Android apps and widgets can’t be installed to a microSD card, and juggling two sources of storage can be a hassle.
So in other words, it’s a tablet which has a battery which makes it certain not to last through the day, tiny amounts of storage, and a dual core processor which is likely to make it feel sluggish. It has no roadmap for future software upgrades. Essentially, it’s barely useable for the kinds of purposes that any family would want to use a tablet for.
Yes, it’s cheap, but in the way that 10p tins of beans used to be cheap: you’d open them up, and find a third of the can was thin watery sauce, with some tough, tasteless beans nestled at the bottom. You’d eat them, because they were the only thing you could afford: but if you could afford anything better you’d buy that instead.
