How well does the spring hold up with use over time (i.e., with inserting/removing units of different height/width across years)?

We just got this device about a month ago, so I cannot answer that. So far, so good. We have it in our jeep on the dash with no bracing and are using it to drive around the city. It does not move. We love it. Hope this helps somewhat.

I ordered this product in March 2012 and have used it moderately to hold two different smartphones and it is still going strong.

I've only had this product for about 4 months and it holds up just fine. I'm actually using it for my Garmin Gps and it holds up really well. Hope this helps.

We have not used it very much so as to the spring holding up I am sorry I can't help you. It does hold the GPS very well and tight. Was hoping to travel more but haven't yet. Sorry I can't answer very well for you

I have used it like that since I've bought it about 6 months ago and it is fine also because of the gas spring it sould never sag or anything

I've had mine for over 2 years now. At that time, the SMH-10 was a "fits all" unit. I have no knowledge about any updated units, but I can tell you that you can either secure it with stick tape or via supplied clamp (I use the clamp). Never had any issues with fit, form or function. I do highly recommend this unit. It's never failed me, and has become a staple every time I ride.

Sorry but no on the years, but do like very much how it cycles now as I can set it anywhere height wise in the pit now...my pumps were cycling on every few seconds in the spring because of the short throw, surprised they even held up...now subject to a power outage I feel real comfortable with the setup as it is...wouldn't hesitate to buy another one for my backup pump at some time...absolutely the way to go, get rid of the short throws on the pumps....no moving parts to contend with...

It takes some modification and tweaking. I had to use some alligator clips and test leads then I pulled the spring a little. Do a search of the web to see what mods or hacks others have done.

About 1-1/2". Sufficient to do the job. Now if you are planning to be moving it around a lot, and not LIFT it up doing so...then I'd expect some problems after a time. I've had this unit since early Spring ('14), and still looking good.

To be completely honest, it has held up pretty good, but I´m always ready to jump (just in case). I´m using it from 3 to 5 times a week (started in 240lbs and now I´m 210).

I've had mine for several years now, use it often and for long periods, and I've not had any problems. I will admit that I go out of my way to take care of my equipment and use it properly.

I've had mine mounted to the frame for over 3 years now without any problems.

It varies depending on the length & thickness of the Spring.You can watch it on YouTube.Thank you

I had mine for 5 years before replacing and I used it quite often. When it became solid I knew it was time to replace.

i looked at my unit a few times to check for wobble,, I was satisfied that the wobble was negligible ,, i can't complain at all. My unit was purchased around 11/2013. Muy only complaint is the tendency of the 1/2 chuck to loosen it's grip on small bit, ie about 1/8 in size.

I haven't used a box spring with mine. But it's been over 7 months and mine has not lost shape.

NO, I would suggest working at it slowly until you make progress. I have the original Bullworker (since 1973 - 40 years - if you can believe that!) The spring has NEVER lost tension. It took me years until I could fully compress it in some exercises.p.s.: I do not like this 'new' model. It is NOT the classic Bullworker - but through time and change of companies they're trying to sell this a 'classic'. Look up Gert F. Kölbel, original inventor of the Bullworker on 'Wikipedia' to get a background story.

Yes very, I've own this one for only a few months and use it a lot. I've had the Smaller version for over 8 years and that still works fine. Just need to tighten the screws every once and awhile

As long as you move into a residence where the height is the same, you can easily remove and reinstall. I have done it twice and it has held up perfect.

Yes, I would think so. The only thing I was disappointed was the spring has already snapped and it won't go back. We just keep it pulled open all the time.
