I'm not that impressed with the things I have.
I would rather have Toptul but, that's another story.
The items I have are durable but, aren't really my favorites aside from their extensions with the knurling on the shaft and the hex shaped female square drive area. I do like the tools' satin finish. I don't care for their 45 tooth quick release ratchets. They're too head heavy, and the action is more clunky than crisp.
Although i have been severely tempted to buy one of their loaded carts on sale, I've managed to resist temptation so far. I think that sonic has one of the better preloaded foam inlay tool plans but, the problem is that aside from the Corvette racing set, their size selections are geared more towards the european car market and by that, i mean cars that are european but, no around the USA like renault, vauxhall, skoda,etc..
The other downside to Sonic is their online prices. When compared to say NAPA's Carlyle (another Taiwan made brand) on sale. Carlyle has a wider range of sizes in most tools geared towards the vehicles found here. If i could only get the satin finish on Carlyle tools.

OEM brand hardline sockets are similar to Sonic's and have the satin finish
I wish Sonic well and visit their site often. I'll continue to buy more of their products when they have things on sale or clearance.
