I have had nothing but frustrations with Nexdome. First it took about 6 months for the kit to come in(I was told 3 months). Then another 3 months for the rotation kit to arrive.
Here is my story:
After looking at the POD and Nexdome, comparing the 2 in reviews(not too many for Nexdome as it is a new product) I decided on the Nexdome because it had a rotation kit available(so I thought). I bit the bullet and ordered the dome+rk. I ordered it through telescopes.net and before placing the order called Nexdome and inquired about time to ship. I was told 3 months. Great! 3 months come and go...I figure I'll wait another 2-3weeks before I inquire.
End of Sept.: 3 weeks later I called and I was told at the end of Sept. Great!
1st week of October: I inquire again. I was told in about a week.
End of October: I inquire again. I was told soon. Now I'm beginning to second guess my purchase. Mid November: Boxes arrive!!! I'm soon happy....but, UPS wants $218 cod. ****? It was advertised with free shipping. I give them a check and then promptly stop payment to figure out what it is. Called customs and it was a broker fee, however, customs told me it was $39 for the entire shipment. Where did $218 come from??? glad I stopped payment. In time, UPS would send a bill for $39(paid it).
So now I start putting it together as I had already had a deck put in(another $600) and as I am removing the panels from the boxes I notice that all the left corners are cutoff and one panel has a crack and one of the dome panels has a hole(like something melted through). I call the seller and they contact Nexdome. Nexdome sends the replacement panels(1 wall, 1 dome panel) and in lieu of the damaged corners, sent me a dome cover. All good but there are missing screws, nuts, and washers so I had to go to home depot and spend about another $50 in hardware. The dome is now assembled and I am liking it. However, the shutter is very, extremely difficult to open. I was given the advice of another Nexdome owner to use some dry lubricant which made it a bit better and easier to open. Still no rotation kit.
Early February: Rotation kit arrives(after threatening to have my credit card company do a chargeback). Install it, follow the instructions on connecting it using ASCOM aaaaaaand nothing. It won't move unless I manually toggle the switch. I contact the manufacturer and he directs me to the person writing the code. I was given some more instructions aaaaaaand nothing.
I left a few of the boring details out but basically I paid close to $4K for what has amounted to be a plastic shed keeping my CGE-Pro mount outside and dry. I haven't used the mount since Nov'2016 in hopes to get the rotation kit installed and working. This has turned into almost a year long frustration. I wanted it to work, I wanted to be happy, but this experience has left me close to quitting this hobby. I now wish I would have bought a POD, at least I would have been using my gear and enjoying the clear nights instead of gazing out, seeing the Nexdome and just feeling so frustrated that I didn't even want to go outside and look up at the sky.
Take my advice. Buy something, anything other than a Nexdome.
