Yes, it is absolutely the same chipset as the MS5308 and a growing number of other similarly-priced clones. Google for ES51919 and ES51920 for more info on the chipset Cyrustek.
Same buttons and screen contents, but each manufacturer offers their own variation of button and LCD screen layouts. the main variants will be in the quality of the accessories and the case. At the quoted price, (plus shipping and local taxes), this variant looks cheap. Either prices are coming down, or this one short-changes you in other ways - you decide.
I own a Mastec MS5308, by the way, and have posted about it here, previously. Unless you have "farmers' hands" (big!) it is not really a hand-held instrument, but a bench one. it performs to spec and I am happy with it.
