Kaisi 45 in 1 Tool Bit Heads Versatile Screwdrivers Set

It's a good and very convenient tool set, the selection of the bits covers next to any small screw heads and nuts for precise work.The only problem is that the quality of steel is pretty far from perfect. About a year ago I bought exactly the same set and use it a work really hard - no complains about quality of steel. It looks like the manufacturer decided to drop the manufacturing costs.

This is one of Amazon's hidden gems, quality tools and carry case easily makes this the best mini/micro driver set I've bought to date. I used it once and ordered two more sets for my father-in-law and an extra one for me.We use this to work on computers, both desktop and laptops, thought the drivers/bit-heads are small enough to work on glasses, cell phones, even SSD drives.There are two things that make this the best tool set we've used yet:First, the screwdriver can change sized: You can use the plastic handle with a driver by itself or use the metal extender for a harder to reach screw.Second and I think this is the best part of this set, the second extender is a flexible arm that allows you to reach around an object and twist the handle which moves the driver. This makes removing or tightening screws in tight placed as simple as can be and can often times prevent me from having to remove the otherwise obstructing object.If I had to find something to complain about, I'd say it's that the extender arms are not secured in the case very tightly and shift around a little. But that's it and honestly, what does it matter how much it moves?Excellent customer service from the seller too, not instant shipping, but still relatively quick.
