GD Grip Ultra 70 Adjustable Hand Gripper USA Version by GD Iron Grip

Very good product

I must say it’s one of the best gripper on the market. Hand span can be infinitely adjusted with great precision. Spring tension is easily adjusted by front knob. There is no clicking sound as in many Chinese cheap copycats (avoid). Very good grip in hand - no knurling on front handle giving it a very good feel in hand. Simple sturdy and light construction -not too heavy as other GD gripper. Needs a bit of grease from time to time on the main nut to keep it running smooth but this is not a problem and it’s very easily done with perfect access. Best feature to me as compared to other grippers on the market is that the handles compress in parallel rather than at an angle as in standard simple grippers. This gives a great feel in hand and it’s properly ergonomical giving uniform action when compressing. Not the cheapest gripper but I don’t regret buying it. Great product from GD Korea.

It's a very good product, but I wished It's handles were covered by silicone rubber to avoid funger pain.

Der Artikel kam in Rekordzeit an, wurde aber offensichtlich schon einmal geöffnet, war also wohl eine Retoure. Ich kann aber keine offensichtlichen Mängel feststellen. Nichtsdestotrotz macht der GD Grip Ultra 70 einen soliden Eindruck. Keine Gummierung, die irgendwann klebrig werden könnte, stabile Plastikgriffe - vermutlich aus ABS - und eine Mechanik aus Metall. Die beweglichen Teile, die am meisten Kraft aushalten müssen, sind ordentlich geschmiert. Ich schätze nach einer Weile sollte man das nachfetten. Vielleicht aktualisiere ich die Rezession nochmal, sollte ich nach einer Weile etwas feststellen, was sich lohnt zu berichten.

I love the smooth action of this gripper. However, it is quite confusing and complicated if you want to dial in precise measurements and increments of resistance. Had to do a lot of searching on Google and watching Youtube videos to get a sense for how you calibrate the resistance. If you want to use this gripper like you would a set of weights, i.e., by starting off at a certain "weight" and incrementally increasing the resistance with precise increments to the loading, it takes work to figure that out and apply it. It also changes the travel of the grip. Lower resistance is very short travel, i.e. short ROM, higher resistance = longer travel = fuller ROM. There is a relationship between the plastic knob, the metal ring and the length of travel of the gripping handles and the resistance you get.
