Good buy!
Got these really to try them out and see how they lasted. Having used them for a few months on and off, they are pretty good. Obviously if you use them on high torque, they will wear out, but they’re ok, and I would re- purchase them.

Top quality
These bits work well and last better than others had for a while now and still using these same ones and only 1has broke so these are good quality and quite fair price As I use them every day I will definitely buy these again

Good enough works well
It's not a bad product, I used one of the heads maybe 6 odd jobs and just snapped on 2 parts of the polz head yesterday. Not bad quality all things considered. It's like everything else in how to connect and all universal the fact its a long neck on it helps on many tasks to reach for install where as using a ext bar isn't always possible. Seems to give a stable contact point when used on my impact driver. The negative i suppose is nothing unique about product so if I need replacement parts I tend shop around for best price for that type of criteria

I’ve used lots of cheap ones and they have only lasted a very short period of time. DeWalt ones are the absolute bomb

Très bien, à l'air costaud.
Semble costaud à voir dans le temps. Bien usiné.

ottima ma non per tutti
Spesso vado a leggere valutazioni di altri acquirenti, e spesso la decisione l'ho già presa prima. quando mi avvicino ad un prodotto realmente PROFESSIONALE è difficile che mi faccio influenzare, su questo articolo in particolare, ho letto una recensione fortemente negativa, (per altro da un cliente non italiano) il quale ignora che per usare prodotti PROFESSIONALI, necessita un minimo di professionalità anche l'utilizzatore, se l'utensile non lo usi in modo corretto, fai presto a danneggiarlo. e ha concluso la sua recensione dicendo che cambierà marca. ( una fortuna per tutto ciò che è per professionisti, non avere un cliente simile) con questo intendi affermare che le recensioni si possono servire, ma non sono la BIBBIA. se un oggetto vi piace e ha una sua storia, non rinunciatevi per una valutazione negativa. Io forse sbaglierò, ma non ho mai recensito un prodotto in modo negativo, quando altri ne son rimasti soddisfatti può capitare il pezzo difettoso, oppure un'aspettativa non in linea con ciò che ci si aspettava!
