Yea man they look alright, good price to. Most are around £20-£35 for a standard set, and going up from there is you want better ones (e.g 2 decimal place, etc).
If you worried about them not lasting, and breaking easily (I would have that concern at such a low price), I own "On Balance - Truweight" scales and they cost me £20 or £25, and I can recommend them.
Also, not matter what scales you buy, make sure you take the precausions they say on the leaflet. E.g, Don't shake, expose to extreme sunlight etc etc, as these things will cause them to break easily.
