From YoYo Wiki

The Viper is a yo-yo made by Henrys in Germany. The Viper was a popular single A yo-yo due to the fact it could be modded before unresponsive yo-yos became popular. Because of the wide soft shells it was also one of the first yo-yos popular for offstring play. The yo-yo comes stock with no response system and high quality ball bearings. The Viper has a unique design with large rubber shells that flair out from an aluminum hub to create the butterfly shape of the yo-yo.

The Viper was the first yo-yo to be released by Henrys. After its success Henrys re-released the Viper so it could accommodate the AXYS system that their newer yo-yos used. The AXYS system is a series of interchangeable fixed or bearing axles that you can buy and swap out in the yo-yo very easily. The classic (non-AXYS) Viper has a conventional axle and bearing system. The classic Viper is the favorite among modders, since the bearing can be replaced or shims can be added. Both versions of the Viper are still sold.

I have Henrys Viper with the AXYS system. The yoyo came double looped and very responsive. After some adjustment and a single loop the yoyo was tug responsive, but still sleeps. This yoyo needs a lot of break-in to get to that sweet spot with the bearing. The new AXYS system does not disassemble and there are not really any shortcuts with cleaning & lubing the bearing. After a few months of play the bearing started softening up along with the rubber shells. Im not sure how popular this yoyo is in today's market of long sleeping, non-responsive yoyo's, but the Viper is still a fun yoyo to play with.

The rubber shells make for soft impact with the hand and any other objects in the house :-) however the light weight of the Viper may be a turn off for some people. The fact that this yoyo is a bit narrow, but has a very large diameter may be a turn off. This is a really good yoyo to use to get practice making your 1A tricks smoothed out. The Viper is also decent for 5A, but not to be compared for other offerings from YoyoJam or Duncan. This is just a different yoyo.

Any more I think this yoyo is for collectors who enjoy playing with a variety of yoyo's. I wanted a Viper for many months and was a bit dumbfounded by the thing when I first started throwing it. After getting use to the size I find this yoyo to be a lot of fun to play with. And with the rubber rings you don't have to worry about breaking anything! --redgrape

I have a Viper classic (gen1) with no mods, all original bearing axle system. I bought it a few months before the Gen2 came out, so missed the AXYS revolution. The rubber rings were a plus since I am a massage therapist and need unbroken fingers and other body parts for work. This was the 2nd tranaxle yo-yo I purchased (the first was a used roller woody. . .ouch) so the response was about what I expected. The bearings on the viper come clean out of the box (at least that was what I was told at the shop) and had a nice quiet whine while sleeping. The response was clean out of the box with a double loop but still produced 3 minute sleeps (my own personal best, no tricks involved). The weight of the Viper was something I needed to get used to since throwing a "No-Jive" and "roller woody" previously made the Viper feel almost too light. The adjustable twist gap is stopped by a rubber O-ring keeping the two halves from twisting each time it hits your palm, but it eventually wears out making the gap adjust with every throw. The biggest downside to this is when the gap gets too wide, it exposes the edge of the bearing and the string can get caught if you are unaware (making an unexpected return trip). The gap is way too small to do many of the newer string tricks and the spin is too slow to keep it going. The yoyo is too light for monster sleeps, but still my favorite yo-yo to learn on. Over all, I love my Viper. I rarely play with my roller woody, and my other yo-yos just make doing loops fun and easy. Easy on the hands, heads and furniture, I recommend this yo-yo for beginners learning how to do long spin string tricks, just don't get too many layers of string in the gap or you will be doing the Knot trick. --bstullis
