Great value for a set of extensions
Great set of extensions for a great price. Quality is on par with similar tier extensions from other manufacturers. I bought for clean room industrial applications and works great for my purposes. Hard chrome plating is high quality and seems they will stand up to daily use.

Longest extension did not work properly
Longest extension would not hold a socket without falling off

Excellent Purchase
These were the lengths that I needed. Both ends fit well. The only con is the packaging, trying to get the plastic pieces out of the female ends. I would buy these again.

So length is less critical than weight?
Here, a good example when some copy/paste page writer lists incidental features far before facts that lead to sales. Many use phones for tool searches....when the length is bottom of page, only complicates purchase decisions. Likely said writer nor editor own tools, so MAIN detail of 3 piece set goes unnoticed. Thinking logically, very little has changed in customer service or marketing in what; 900 years? But continual survey expectations weedle in hope of some brilliant nugget. x Toolmaker51

The ling and short of it…
This set of extensions are a quality forging and took my torquing like champs. I was able to extend my reach using the longest attached to an elbow socket that then attached to the shortest, which was connected to a 10mm universal swivel socket to reach a bolt under a pump. Saved me a ton of time!
