I don't know anything about the
Wanhao i3 but just looking at the design/specs here are my thoughts:
1. Based on the Prusa i3 design (as are 99% of of budget printers)
2. I'm not sure if the frame is good or crap, it's metal and bulky which is good because you want as rigid a frame as possible, but it's also sheet metal which can be flimsy if the bends aren't made right so... ? Looking around I see people selling these add-on braces:

3. it has a heated bed which is a big plus over most bargain printers
4. LCD is touch screen which is gimmicky IMO I usually prefer buttons or a knob, also it's not angled which will make it a bit annoying to use, not a huge deal though.
5. build area and temp ranges are all what you'd expect for a Prusa i3 clone. you wont be printing any exotic material or anything too big but it could definitely print most of the stuff I've released.
6. it looks like it uses an aluminum bed with buildtack I had problems with a similar setup warping on me under heat, though with such a small bed it might not be an issue.
For the price it's a bit more expensive than some i3 clones but still quite a bit less than most "name brand" printers. However, it looks like it's pretty well built and it appears to include a warranty which means they at least think it will hold up over the warranty period.
I'm not a big fan of the i3 design, it's difficult to enclose if you want to do stuff like print (well) in ABS and they're on the small side. the frame design means that if it's mis-aligned you can end up with prints that aren't square and the Y-Axis moves the bed which means larger (heavier) prints can slow down the stepper motor and cause issues (though might not be as big a problem with such a small bed).
My current recommended printer for new comers to the hobby is the FolgerTech FT-5:

the FT-5 has a nice big print volume, a glass bed, a sturdy outer frame, X and Y move the hot ends while the bed only moves up and down and because it's cube it's easy to build an enclosure if you want one. The price is very good for the amount of printer you're getting too. Though it's nearly £100 more than the Aldi printer so...
