Hi Quetzalcoatl,

Thanx for providing the Bubbleman video. I really like this guy's style. He is articulate, adequately focused on the aspects of the Grasshopper that matter to him, and I don't believe that I have seen a vaporizer review in a more spectacular setting than this. Schwennnnnnnngggggggg ! He is now my co-favorite vape reviewer, alongside Vape Critic. Our community is very fortunate to have them on our "team".

i found that video funny. :) the bubble-guy was knocking Hopper on table pretty hard and was blowing into chamber to get ABV out. don't know about knocking, but blowing particles into heating element is no good for sure. very noticeable that he didn't wait not even one year for Hopper to arrive. but it's all good! he promised to test it hard and report any breakdown.

Seems like the Ti's are having less issues with the back ends tho. Not sure if there is anything to that or not but it feels like most hot back end issues are SS related.

They did write back and say that they want me to send it in, they weren't sending a new back end out. Weak.

Guess I'll wait for my Ti order.

Hi Ratchett,

To add to my earlier comment, I suspect that back-end heat issues might be attributed to a compromised connection between the battery/body and the back-end itself, perhaps due to a failure to fully thread the two pieces together for a positive connection. I would think that even a tiny bit of residue on the threads which are CNC-machined to precise tolerances. could have the potential to prevent proper threading. The Grasshopper has no wires. It relies on inductive pickup for electrical pathways. Therefore, moderately close attention paid to the threading process post battery change seems to be in order. Just sayin',

By design, there is no heater in the back-end of the vaporizer. There should technically be no *heat* produced through normal operation of the vaporizer.

If your backend is hot, there is an electrical short - electricity is arcing between two spots and it is generating heat outside normal parameters. In my book the part is defective and needs to be repaired/replaced immediately. I would suggest you stop using the vaporizer until you get it repaired. Moreover I would remove the battery from the vape to stop the short from occurring and draining/kiling the battery.

I had a titanium GH for several weeks, not once during the entire time of *heavy* use did the backend become "hot" - moreover I never once noticed any heat being produced by my loaner GH.

I am not a GH employee, but I am an engineer at heart. The *only* place you should feel the heat is from the air intake holes and towards the mouthpiece. I personally would STOP using any GH which is producing heat from the backend.

hmm, maybe i will send it back. What do you make of this ratchett?

Hi There,

I am sorry to hear your Hopper is giving you trouble. The Back End will get warm with use, but should never be burning hot. If you feel that your Back End is getting too hot, we are happy to test your device and determine if this needs to be replaced. For us to do so, you will need to send your whole device back to us at Hopper Labs, 2775 Valmont Road #3, Boulder, CO 80304.

If you touch the Back End and Body at the same time, you will notice a circuit is being completed. Power flows to the Body and Button and if you bridge between those two, you will feel a small charge. This is totally normal.

Please let me know how you wish to proceed with your hot Back End.

Best,
Caroline

I guess its safe .. or is this why it keeps dying ?, sometimes I wish we could see like build log like video game designers do, so we can see the "bug fixes" listed every "change/upgrade" they do

very interesting point. what you say about idea to put on those threads a water-based lubricant to increase connection between body and backend? that could help electricity to travel more easy, right? or maybe a graphite powder could do?

I would not apply anything to the threads. Just keep it very clean. Wipe down every so often with ISO. If it can't make proper connection with clean threads then it should be replaced.

That's interesting because I only notice the bridge on my SS and not on the Ti. Like I've said before the SS backend does get hot and my Ti one doesn't. I have recently had the flashing blue/red lights on the SS, so it may be faulty and that's the reason the backend is getting hot. I also tried my Ti backend on the SS and it didn't get hot. I have sent my SS back to them to diagnose it. They replied fast and asked me to send everything back.

Hi Vaperist,

I would recommend using a special lubricant which is inert, and intrinsically safe, and designed for metal applications. Any decent hardware store or electronic supply house should have just what you need. Although, I know absolutely nothing about the relevance this advice may or may not have there in Latvia.

the question is- do i need it? theoretically, is better connection could result in cooler backend?

Good question, I doubt that's the problem though. It can't be that easy or else GH labs would have approved it or brought it up. If it could be an easy fix I think they would have started doing that, applying lubricant, from factory or at least mention it to buyers.

Hi Vaperist,

Although I am somewhat reluctant to delve into matters metallurgical, I must. Briefly.
Grade 4 titanium is super fucking hard. As a result, the male/female thread interface never actually "wears in", like say aluminum, or even stainless steel. No problemmo, however, the significant frictional co-efficient that exists when CNC-machined titanium threads interact, is exacerbated by even the most minute contaminant. There does exist machine oil which meets all of the relevant criteria required for this specific application. It is super common in applications where electricity is involved, and usually also involves mediation of dissimilar materials issues. Is this helpful ?

I am wondering whether extra fine graphite dry lubricant could be helpful in keeping the threading easy and conducting any required electrical flows?

So, the threading on my Ti is way smoother now than when I first got it. I don't think it's that big of a deal, so I won't worry about lubricating it or anything like that. It works really well and the backend does not get hot at all, even if I grasp it near the clip. That said, I don't think anyone should worry about having to lubricate it or even think about it as an issue. It gets better over time and shouldn't be a concern.

Hello,

My main point is that it is likely that the common issue of hot backends may be attributed to less than perfect contact between the backend and the battery/body. Grasshoppers use inductive pickup for electrical transmission via the metal shell, instead of wires, which is fucking brilliant. Any impediment to threading the two pieces together, like shit snacks, fer instance, might prevent a perfect mating of the two electrically related components. IF you choose to apply a lubricant to the threads, like I am, you must ensure that said material is intrinsically safe for electrical applications, as well you must ensure that all other functional criteria are met.

Okay, so what is it? Are you referring to a dielectric grease.
You know I want to be ready, in case I ever receive my hopper.

Hi Vapzilla,

Yes, dielectric grease. Thank you. I purposely did not mention the word "grease" as this would surely cause the slope to become quite slippery, indeed. I am standing in the pre-order purgatory line, still. So I have not physically made Grasshopper contact. Once I have my titanium Hopper I will examine the tpi, cant, etcetera of the threads and decide if the careful application of a "friction mitigation facilitator substance" is wise/prudent. Amen, somebody.

Excellent!
I thinks it's really funny that days' worth of discussion about lubricants and electric current and stuff pretty much spawned from the nose grease suggestion I made to you.
Your threads getting better is great and demonstrates one wonderful aspect of time; it can sometimes effortlessly accomplish that with which we struggle.

Yeah that's why I didn't worry about it. I was just happy with the performance of this Vaporizer. I used to use my Mighty when I wanted to be blown out of my mind, and I haven't used it ever since I got my Grasshopper. It feels so tedious now compared to loading it and being high in less than a minute with the GH.

Your story makes me pleased, though even more impatient, that my preorder is fo a Ti.
I guess I'll suffer along with Mighty until my Hopper arrives.

Thanks, I was hoping I could help those that are worried about the threading.The Mighty is still awesome though, I just don't use it much because I need to be discrete in my studio and the GH is perfect for that. I take a hit use a smoke buddy and the smell is almost nonexistent. I'm also not forced into having sessions, but I wish I could use my Mighty openly without worrying about the smell. Oh, and you'll love the Ti in my experience it does heat up and produce vapor faster than the SS. However, the flavor is a bit better on my SS. When I get it back I'll see if that's really the case with or if it's because my SS is defective.
