I have one but only owned it for about 2 months. My concern is how will the plastic hold up, but it's done ok so far. haven't used it much.
I don't like that it's not a case, and donesn't protect the sockets so wherever you intend to use it probably wouldn't be 'heavy duty' ie its own pocket in a backpack/tool bag etc. It's not as bulky as a case either so that can be an upside.
it's not as simple as open the lid of a box and get your tool, they use a combination of hinges, slides, and twist lock. It's not likely to be anyone's main socket set but the two time's i've used it i forgot both times it doesn't have a 5mm.
if you have other wera handles (the esd safe for instance) with the larger bit retention they do not fit on the side there so you could not use this as a platform for making yourself a more customized kit, in that regard at least.
For the price they are good tools although depending where you are you have a lot of bits (and a few duplicates i think?) that you may only use a few, and a fairly limited socket sizes combined with trying to turn a bolt with a 10mm head with that tiny ratchet may only be useful in limited situations if this was the whole of the tool kit you have to work with, means this can only be complimentary in certain situations. Just keep that in mind before you go nuts over the amount of the discount you aren't really getting a whole lot of kit for the price relative to other (albeit lesser quality) kits available commonly.
