Great neck tool set
Style: 125 Piece
The tool set arrived and I was surprised that the case was good quality and fit nicely. The tools are of medium quality but work when you need them. My kit had two of the same offset screwdrivers and Great Necks customer service was responsive and polite and sent me a replacement part quickly. The only negative thing I've found is that some of the tools in the upper lid don't stay in their places when you open the lid. A couple of small holes and some tie wraps should fix that. Over all this is a great product for the boater. ... show more

Lots of tools

Great price and lots of tools. Great case. Sometimes the tools fall out but overall good buy for my boat.

An Emergency Tool Kit is just what it is
Style: 125 Piece
Several reviewers have commented on the quality of the tools, which i average at best. For the price it seems adequate. The 125 pieces is, I presume, accurate - but they include 11 flimsy cable ties and a sealed package of what looks to be about 40 low quality, assorted crimp on electric connectors. So interpret the 125 pieces accordingly. The best part may be the case - with six edge clips to keep it shut and a rubber seal, I am hopeful that it will dlow down the rust enough do that the tools are usable if they are needed. And the tape measure is A JOKE!! It was wound backwards on the spool, so that instead of automatically retracting when pulled out, it automatically CAME OUT and had to be stuffed back in against the spring. IMPOSSIBLE!! Lasted half way through the first use. No quality control at all it seems. ... show more

Horrible product.
Style: 125 Piece
Product is extremely disappointing…….very cheaply made tools, and the case was ripped in two when I took it out of the box. I bought it because it was the most expensive tool box and thus I figured it would be the best quality. Turns out it was probably the worst option. I’ve returned it for a full refund. Do not buy this if you are looking for a quality item. ... show more
