There are few tackle brands I trust totally, knowing that it is right first time, but Gardner are one of those that I have not ever had a dodgy item.
In the 1990's I bought a Gardner Landing Net. It lasted until 2004 when it was stolen, I don't recall even replacing the mesh. Gardner hooks I have found blooming (as in to make bleed figuratively and literally) pinprick sharp straight out of the packet. I used their PVA mesh bags for years, and I haven't changed from Gardner Pro line other than a brief flirtation when no-one had any in stock after Richard Gardner sent me the sample batch to test myself before its release.
If I ever contemplate moving away from my Delkim loyalty (I've never had any problems) the only alarm I would switch to would be Gardner. I did play with the original TLB's and the wired sounder, they were nice and did look good.
