  • Thank you , the best tools for the boat
Style: 191-piece
the best marine tools fixing sailboat on the ocean .Good quality .
Reviewed in the United States on August 17, 2023 by RIMAS MELESHYUS

  • Cheap tools
Style: 191-piece
Ordered this for my boat so I would not need to bring my expensive ones. The quality is poor compared to other tools. The case is ok and it is convenient to have basic essentials organized but durability of tools is poor. You can feel the difference in cheap flimsy tools when using. The socket ratchet is so bad that it wiggles and changes direction sloppily. Pliers remind me of the cheap Chinese crap that they pawn off and electical connections are a disaster. ... show more

  • Good selection of tools, case issues can be mitigated
Style: 191-piece
I was concerned about everyone who said that the case is lousy, and indeed mine arrived with many parts having fallen out of their designated locations. I solved this my cutting a part of the box to fit between the two sides -- this holds everything securely! I'll have these on my boat, so time will tell about durability and corrosion-resistance, but my first impression is mostly positive. ... show more

  • Boat tools
Style: 191-piece
Good kit to keep on the boat for small or last minute repairs, the only draw back is that some of the tools do not stay in the designated space in the kit.

  • Not All Tools are Chrome-Plates
Style: 191-piece
The plyers are already spotted with rust even though I've never used them and kept them in the case on my sailboat. I was hoping to get a toolset that would be more resistant to the corrosive effects of marine air; for the most part, this kit does it, but not as well as I expected or would have liked. ... show more
