I've not ever dropped it or anything and it still failed me gradually... i think it should've lasted longer but it's been some good long years so it's fine... my new one works perfectly. To be honest the price is quite high too but I haven't come across anything better so I can't complain. Overall it is a great thunderbolt adapter ### ⭐⭐⭐⭐⭐ Ideal for Apple cinema monitors *by on Reviewed in the United Kingdom 24 September 2019* Like many people who have bought a new Apple laptop recently. The move to USB-C / Thunderbolt 3 has been extremely disruptive. I spent a fortune on new accessories. One thing I wasn't prepared to do was throw away my Belkin hubs and Apple Cinema monitors. I tried Apple's own Thunderbolt 2 - Thunderbolt 3 adapters; and they worked inconsistently. One day I would switch on my computer and the monitor or hub wouldn't work. For no reason. StarTech are a respected video brand, who used to make a well respected Thunderbolt 2 hub, so in desperation I decided to give their adaptors a chance.Let's get the negative aspects about them out of the way first. They are bulky, with the electronics coming in a case about the size of a stack of playing cards, rather than a small pack of chewing gum like Apple's own convertors. They're in a shade of dark grey only a sys.admin could love.But once you get over these cosmetic issues you get a product that just works. It is ironic that I had to go to a non-Apple supplier to get this most Apple of attributes. I can wholeheartedly recommend these convertors. ### ⭐ Junk. Doesn't work. *by on Reviewed in the United Kingdom 5 June 2025* Doesn't work. Or rather worked sporadically for one day before stopping. Not recognised by Mac Studio M1. Apparently incompatible with Thunderbolt 4 even though 3 and 4 are supposedly reverse compatible. I missed the returns window so it is money down the toilet. ## Frequently Bought Together - StarTech.com Thunderbolt 3 to Thunderbolt 2 Adapter (Non-Reversible) - TB3 Laptop to TB2 (20Gbps) or TB1 (10Gbps) Devices / Displays - Black - Windows/Mac (TBT3TBTADAP) - chenyang Thunder-Bolt 2 Port to Thunder-Bolt 2 Male to Male Video Data Cable for Mac 2013 2014 2015 2.0M --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/48338173-startech-com-tbt3tbtadap-thunderbolt-3-to-thunderbolt-adapter-windows-mac](https://www.desertcart.com.au/products/48338173-startech-com-tbt3tbtadap-thunderbolt-3-to-thunderbolt-adapter-windows-mac) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-09-01*
