I agree with rsmstar the developer does provide really good support and response times.
As a developer myself I don't really like that most of the files are ioncube encoded, so I can't extend off/modify any code for in house needs.
Also as of writing the syncing process is literally real-time which means if it fails and there isn't a check in place to gracefully error out then the whatever was about to happen (placing an order, saving a product) can/will fail as well. This simply doesn't work for our needs and the developer has been fairly good in working with us to come up with a solution to meet our needs.
All in all its been a good experience, just a few times where the module failed for whatever reason and our store wasn't able to either save products or take order which is a must for our business. Look forward to getting this resolved asap.

Most valuable extension of our Magento installation. We use it to push Magento customer data to Contacts in Salesforce and push orders to Opportunities. Product integration is also available, and you can also add the products from the shopping cart to the Opportunity as a line item if you wish to.
I like the flexibility of Magenforce and I was easily able to get started and configure it to match the way we use Salesforce.
Another big plus is the support of the developer. Issues are quickly fixed and missing features were added at our request.
At this moment the extension is updated every week to cover new features and as you can read a two-way sync is coming.

The extension is still being worked on. Due to the nature of the product, majority of our work goes into helping our customers adding support for other 3rd party Magento extensions. Next big release will enable 2 way sync between SalesForce and Magento.
