I haven't used the app-control yet, but, controlling via ASCOM was pretty simple! With guiding from PHD2, and a bit of tweaking to my settings, I've managed 6 minute exposures with minimal star trails. The mount itself seems very well built, and assembly was easy! - The tripod could be a bit more sturdy, but, for the price its perfectly acceptable!

This is a good mount for the price, but the GoTo is WAY off; even after a 3 star alignment. Hard to align without the azimuth adjuster, but it's possible. The image below was achieved with bad polar alignment, 30 second exposures. Update: got the GoTo working.

I've been looking for a small goto mount and the iEXOS-100-2 fits the bill nicely. It was easy to put together, well made and my SVBONY MK127 goes well with the mount. The weight of the whole system is good; it's not difficult to move around and in the limited testing I've done so far, it's pretty stable. The mount comes with a battery pack, but I'm using a Celestron Lithium PowerTank instead. I found the PMC controller to be fine. Explore Scientific has open sourced their controller software and there are options to control the mount remotely. While it would be nice to be able to control this mount from an app like SkySafari, the Android app is fast and adequate. I'm not an Android person, so it took me a while to figure out how to unzip and install the control app, but once I did, the cheap Android tablet I was using had no problems controlling the mount. The app will run on an Amazon Fire tablet as well. Aligning the mount with Polaris wasn't that difficult.

I had pretty low expectations of it considering the price, but I was pleasantly surprised at its performance. It carried my Redcat51, 533mc pro, sv165 guidescope and 122mm guidecam like a champ, getting around 1.5 arcseconds variation in the ASIAIR's PHD reading. I think with a slightly lighter OTA or camera, or maybe an additional weight to balance the assembly better on the RA axis it would perform much better. Also polar alignment would be easier with the optional azimuth plate. But all in all, I'd consider this mount an absolute steal. It's significantly quieter than my other mount and is very easy to connect to a PC or ASIAIR to control it. I haven't used the included app so I can't comment on that. It's so nice to have a quiet, light mount that can autoguide and be run by my usual software. Here's my proof, a 2 hour image of the Crescent Nebula in HOO narrowband taken from a Bortle 7 location.

Who even builds a mount with no azimuth adjustment? Nobody except explore scientific. Another 120$ for that feature and I found it didn't thread on enough for my liking so I cut off the flange on the adapter to get a better bite. Hopefully you get instructions with you adapter because I didn't. I had to watch a video about removing backlash and fix that. The polar site hole plug falls right out, it's a very poor fit. I had to tighten every tripod leg, they were all loose. It seems there's a reason why it's on sale. You get what you pay for. I haven't had a chance to see how it tracks yet, I surely hope it's nothing short of amazing after spending all this time fixing what research and development didnt.

I have not had a change to use this mount a whole lot so i will update more in the future. As of right now the mount seems to be rock solid. It holds my Orion Eon ED80 , 50mm guide scope and dslr just fine. The counter weights were just a few ounces too light to balance it so i added some sticky car tire weights to them. The Explore stars app is only available through the Microsoft app store. Which was tricky to get it to work but after some great help from Explore Scientific i was on my way. This is my first telescope and mount so i dont have a ton of experience. After initial alignment and setup it was smooth. I have not done any photography yet with this mount due to bad weather. I should be able to get some done this weekend and will post an update. Over all for the price and quality and support i dont think you could find a better comparable mount for the price. Update: I orderd this item on July 26, 2019. It is now May 2 2020. The Mount its self is well built for what it is. The major problem i have is to make it functional you have to spend a ton of money. I had to purchase a polar scope for it. Which has next to no instructions. No real way to have it in the same spot each time you take it out. Which was not available at the time of purchase. At the price of approx $90 shipped. You have next to no azimuth adjustment. However they will sell you an adapter for $100. They also offer an upgraded tripod for the mount. At a cost of $250. Which requires the special azimuth adapter in order to use it. If you buy this mount and all the other items needed to make it stable and functional you would still not be able to do much. Because the software is complete trash. Tried on several android devices. Half the features dont work. Crashes all the time. Same with windows laptop. The software also makes fine tune adjustments impossible because you cannot look through a scope and look at a monitor at the same time to see where you are doing. So by the time you are done spending 800.00 on this setup you could just buy a mount that will hold more weight and be more functional. The only redeeming quality is its light weight and customer support is fast to reply. I have not been able to get this mount to properly function with any software i used. (PHD2, APT, Explorestars ) I did the latest firmware update. I purchased a new mead lx mount . I was up and imaging with in 10 minutes of setting it up outside.
