I have used this repair kit many times. I can't rate their durability as I don't need to use them on a daily basis, but they certainly got the job done with no issues. The body is solid and well organized. If my only complaint was that accessing the tools is a little painful. There are no cutouts under the taps or dies to remove them from the recess in the plastic shell. The tablet itself is a little flimsy and it's difficult to remove the top tablet to access the one below as the tablet has no handles or notches that allow for a firm grip of your fingers to lift the tablet up and out of the case to pull . For my use, which is a very rare and occasional fix, this is definitely a good buy for the price, but if it's something you have to use every day you'll be very annoyed by the filing system. I would buy it again if I had to install it just because of the quantity and the different sizes that are included.
